Nanolab

Nanolab Nanotechnology Nanoelectronic Lab FACULTY & STAFF Research fields Laboratory Equipments Research Projects Design and simulation Nanotechnology Nanotechnology One of the most important aspects of nanotechnology is its multi-disciplinary aspect. The current structure of training program in most of the universities has some shortcomings for nanotechnology experts. Therefore training programs need to be optimized. The factors by which the way toward long-term goals of nanotechnology is being provided in time period less than 20 years are as follows: establishing research centers and applied laboratories of nanotechnology and multi-disciplinary research programs and groups in universities. Hundreds of billions of dollars investments in the field of nanotechnology by developed countries like Japan and American indicates the nanotechnology’s universal importance. In Iran there is a great deal of scientific potential in order to conduct nanoelectronic researches. As a matter of fact, published articles in authoritative international journals and successful research projects represent that there is little distance between Iran and developed countries in this field; therefore, the competition is possible. Research contexts in this laboratory include the factors like quantum transmission, single-electron devices, applying nanoparticles to fabrication of photodetectors with ZnO and molecular nanoelectronic. It has been predicted that by means of equipping the laboratory in future, it is possible to conduct practical activities like using electronic microscopes in order to measure atomic dimensions and molecular ordering, identifying three-dimensional features and nanoelectronic device surface, controlling molecular ordering and fabrication of photodetectors and so on. Nanoelectronic Lab Nanoelectronic Lab Nanostructures can be metals, semiconductors and dielectrics which at least one of their dimensions is in nanometric range. This characteristic causes quantum confinement of electron motion and dependence of physical properties into the material dimensions. In other words, by decreasing dimensions of semiconductors, their behavior is complicated and new physical phenomena occur such as electron ballistic transport, tunneling, columbic blockage and so on that this in turn causes change of electrical and optical coordinates of devices. Therefore, it is important to investigate and explain these behaviors, obtain of electron motion equations and wave function and finally simulate and use of these property in nanoelectronic. Nanoelectronic Lab includes two fundamental fields of molecular nanoelectronics and semiconductor nanoelectronics. Semiconductor nanoelectronics has three subsection of single electron devices and quantum dots (SET, QCA, RTD,…), nanofilms and nanofilters (TiO2, ZnO, …) and photodetectors and photocatalysts (Si, SiC, GaAs, ZnO, TiO2,…). Also, Molecular nanoelectronic filed has two subsets: molecular transistors and molecular cellular automats. Fig. 1: Comparison of nanotools. Fig.2: Taxonomy of Nanoelectronic devices.

Research fields Research fields Fundamental research fields of this lab includes:  Investigation and analysis of quantum transport  Modeling of quantum transport in nanoelectronic devices  Simulation of these models for nanoelectronic devices  Fabrication of nanoelectronic devices Fig.3: research fields of Nanoelectronic Lab. Laboratory Equipments Laboratory Equipments Research Projects Research Projects  Design and fabrication of Titanium Oxide thin film containing Ag nanoparticles Sol gel process is a very good method for fabrication nanometric oxide films. This route has advantages including very high chemical purity, ability of phase change control and so on. After preparing sol, by using spin coater apparatus and choosing desirable pressure and speed, homogenous layer is formed on the substrate (quartz or glass) and is annealed in oven. Then, Produced film is analyzed by UV-Vis spectrometer and absorption and transmittance spectra of thin film are obtained. Fig. 4: Sol formation stages. Design and simulation  Design and simulation of dynamical circuit model for QCA cells QCA dynamical cells are modeled and simulated by using equations obtained of kirchhoff's voltage-current circuit laws and equal circuit design of QCA clocked circuits. Dynamical relations of Pauli spin matrix and following dynamical relations of coherence vectors for Design of dynamical circuit model can be obtained from calculation of Hamiltonian circuit and using Heisenberg image relations. In mathematics expression of coherence vector, a part of state variables is related to correlation between QCA cells. For this resean, temporal depecdence of elements of correlation matrix of two cells is calculated and therefore complete equations of QCA dynamical model are obtained. Fig. 5: QCA cells.  Design and simulation of Ag nanoparticles effects on electrical and optical coordinates of Titanium Oxide thin films By using numerical methods, effects of diameter and figure of nanoparticles on electrical and optical coordinations of titanium oxide thin film are investigated. Some of them are absorption, diffraction, reflection, transport and energy gap. By using optical parameters, refraction and dielectric coefficients and conduction can be obtained. In addition, polarization, absorption and reflection of n doped layer can be obtained. Also, Ag nanoparticles effects on quantum efficiency, optical current, dark current, noise, NEP and photodetection ability in TiO2 photodetectors are analyzed and simulated.  Design and simulation of single molecular transistors MOSFET size reduction results in decreasing of cannel length to a few tens of nanometers. Hence, in general all device dimensions including oxide thickness, attachment depth, length and width of cannel and isolation distance change and quantum effects will be dominated. Fig. 6: Design of single molecular transistor. In simplest model, a molecular device includes one molecule that attached to two metal electrodes that have roles of source and drain. Complicated goal of molecular electronic is implantation of a molecular transistor with three terminals which can switch current between two branches by changing applied external electrical field to the third branch of individual molecule. Effects of applying external electric field in direction of molecular length as drain-source voltage and also electrical field perpendicular to transport direction as gate voltage onto the applied field molecules are investigated. Effects of increasing acceptors and donors groups in benzene molecule to the parameters of chosen molecules and calculation of voltage-current properties are studied. Fig. 7: Model of single molecular devices.  Investigation of single electron components and transistors Single electron tunneling transistors are devices which using tunneling quantum effect to control and determine electron movement. Single electron devices include single electron transistors (SET) and single electron memories (SEM). Their advantages are low consumption power, high switching speed and their ability of increasing density of integration. Unlike field effect transistors, single electron devices work according to quantum phenomena (tunneling effect). In these devices, some electrons which have Fermi energy can tunnel through dielectric material even in classic condition that their energy is much lower than necessary energy to dominate on the potential barrier.  Design and simulation of ZnO based UV photodetectors with improving of quantum efficiency & dark current In this project, the current transport mechanism of ZnO-based metal-semiconductor-metal ultraviolet photodetectors with various contact electrodes is discussed and simulated. The simulation is based on the thermionic emission theory and tunneling effects. It was found that the lowest dark current, 6.04×10-10A at 3V biased, is obtained when the RU contact electrode is used. Moreover, it is shown that in order to achieve a large schottky barrier height on ZnO and more reduction of dark current, one can insert a thin oxide layer between contacts and ZnO layer. Also, the influence of the thickness of the insulator layer on the dark current of the MIS photodetector has been analyzed. Based on the simulations results, the dark current at 3V photodetector biased, with various thicknesses of interfacial insulator layer 3, 5, 7 and 10nm is 2.87×10-11, 8.23×10-13, 2.36×10-14 and 1.15×10-16A, respectively. Furthermore, quantum efficiency in our simulations with an antireflection coating has been improved. It is found that in these devices, the quantum efficiency with TiO2 thin oxide with thickness of 1nm is 46.7%.

NRC Research Groups

Research Groups Optoelectronics The main research activity of this laboratory is based on the industrial and semi-industrial projects in the field of optoelectronic and semiconductor devices. These projects are done by the PhD and MSc students. Some of these works are the design and simulation of photonic crystal devices, photonic crystal fibers, semiconductor lasers, photo detectors, solar cells and so on. At present, the most researches in this laboratory are on the solar cells. One of the projects is being done in order to fabricate the laboratory sample of solar cells based on GaAs. Firstly, the design and simulation of the proper solar cell structures such as GaAs and AlGaAs/GaAs has been done. Then, the fabrication of the primitive sample is being done with choosing the best structure and finally the final sample will be fabricated after the test and optimization of samples. Also, one of the main issues for improving the solar cell characteristics is utilizing the suitable antireflection coating and presenting the novel structures for it. In order to achieve these purposes, we are working on the antireflection coatings used in new generation solar cells such as thin film and quantum dot solar cells and cells based on the concentrators. For more information please click here Quantronics Quantronics is composed of two words: Quantum and Electronics. Thus contains two scientific fields. The main research activity of this laboratory is quantum communication and optical quantum computation. Quantum entanglement lays at the heart of quantum information processing (QIP), which over the past twenty years has become an emerging field of modern physics. QIP can mainly be divided into the two areas of quantum communication and quantum computation. Quantum communication describes the transfer of quantum states over large distances, which can lead to drastic improvements in security – quantum cryptography – and channel capacity – quantum dense coding. It further covers the distribution of bi- or multi-partite entanglement between different parties, separated by large distances. Quantum computation is dedicated to the implementation of algorithms that exploit the superposition character of quantum entanglement to dramatically speed up computational tasks such as a reduction of time needed to search an unsorted database of N elements. Any classical algorithm necessitates N operations to accomplish this task, whereas a quantum algorithm only needs N1/2 operations. Probably the most famous quantum algorithm is Shor’s algorithm to factorize large numbers. Its introduction in 1994 has jump started and fueled tremendous effort in the new field of QIP, both on the theoretical and experimental side.

The current structure of training program in most of the universities has some shortcomings for nanotechnology experts. Therefore training programs need to be optimized. The factors by which the way toward long-term goals of nanotechnology is being provided in time period less than 20 years are as follows: establishing research centers and applied laboratories of nanotechnology and multi-disciplinary research programs and groups in universities.

For more information please click here Systems A reliable attitude determination system is essential for a space mission to be successful. An attitude determination system tells to the spacecraft or satellite how much it must turns until its reciever and sender place toward the earth and also its solar arrays place toward sun. There are several meaturment instrument such as gyroscope, sun sensor, star tracker that can provide attitude information. Amoung them, star tracker ‎ is the most accurate one. A star tracker allows attitude estimation without any previous knowlage of spacecraft attitude. Also they can provide 3D information. Besides, they do not need any extra instrument to provide attitude information. A typical star tracker ‎ functions as below: Camera of star tracker take an image from stars in the sky. An algorithm that calls centroid algorithm, extract stars from image. A star identification algorithm extract some features from these stars. There is an on-board data base which is generated from all sky stars that have a certain magnittude. This catalogue contains the same feature as star identification algorithm extract in previous step. The data base is constructed from existent star catalogue such as hyparcos and bright star catalogue. The features which extract from the image of stars, compare with the features in the catalogue. Wherever they match together, the attitude of spacecraft can be estimated. A star tracker operates in two different mode: initial attitude acquisition mode and tracking mode. In initial attitude acquisition the previous attitude information is not available so the data base must search completely until a match is found. When attitude of spacecraft was found, star tracker enters tracking mode. This mode is the normal operating mode of star tracker. In tracking mode, there is no need to search whole data base and just part of data base which is near the previous atittude is searched. In this paper our focus is on the initial attitude acquisition mode. A lot of algorithm for initial attitude acquisition is introduced. These algorithms can be place in two different classes. In the first class, stars consider as vetices of a graph. Different features can be extracted such as: distance between two stars, angulares or area which three stars create together. Polygon algorithms such as planar triangles ‎ , spherical triangles ‎ , oriented triangles and pyramid algorithm categotises as this class. The algorithms which places in the second class, assotiate each star with a well define pattern that can be determined by the surrounding star field. Grid algorithm, neural network and genetic algorithm place in this class. We are working on a prototype of star tracker that have this ability to become commercial star tracker.

Through the development of the Nanoptronics Research Center, Iran University of Science and Technology has dedicated a welcoming atmosphere for researchers and students interested in the field of Nanoptronics. This center is significant in conducting research, managing semi-industrial and industrial projects, creating appropriate opportunities for conducting M.Sc and Ph.D. student projects and researches, educating experts necessary for various centers and industries, and so forth. Immigration of scientists and educated people from Iran to western countries is not only due to economic reasons, but also due to under equipped and under developed laboratories. Providing scientific and academic advances can highly increase their return. The Nanoptronics research center can meet scientific and human development demands, prospects of medium-term and long-term plans, and specialize in electronic-related sciences. The center has been created as a result of the Nanoptronics sub-major (branch of study) in the Electronics faculty of Iran University of Science and Technology, and the necessity to develop related laboratories. According to the guidelines mentioned, research priorities and our country’s requirements, this center was established in 2007 with the following laboratories:1. Nanoelectronic Lab. 2. Optoelectronic Lab.3. Quatronics Lab.1. Nanoelectronic laboratory: One of the most important aspects of nanotechnology is its multi-disciplinary aspect. The current training program structure in most universities has some shortcomings for nanotechnology experts. Therefore training programs need to be optimized. The factors by which lead the way toward long-term goals of nanotechnology are being provided in a time period of less than 20 years, and include: establishing nanotechnology research centers, applied laboratories, and multi-disciplinary research programs and groups in universities.Hundreds of billions of dollars investments in the field of nanotechnology by developed countries like Japan and America indicates nanotechnology’s universal importance. In Iran there is a great deal of scientific potential in order to conduct nanoelectronic researches. As a matter of fact, published articles in authoritative international journals and successful research projects show that Iran has had great success in this area, leaving a minor distance between Iran and developed countries in this field, making competition all the more possible. Research contexts in this laboratory include studying quantum transmission, single-electron devices, applying nanoparticles to fabrication of photodetectors with ZnO and molecular nanoelectronic. It has been predicted that by means of equipping the laboratory in the future, it will be possible to conduct various experiments with tools, including the electronic microscope to measure atomic dimensions and molecular ordering, identifying three-dimensional features and nanoelectronic device surface, controlling molecular ordering and fabrication of photodetectors and so on.2. Optoelectronic laboratory: Measurement systems and accurate optical instruments are important requirements of different industries particularly those related to semiconductor device fabrication, optical lithography and mask production. In optical lithography processes, it is necessary to take care of nanometric accuracies in measuring mobility of different axes. Moreover, other practical instances of optical measurement equipments include calibration of laboratory and industrial equipments, accurate cutting, robotic systems, surface roughness measurement, and geological sciences and gravity measurement. Obtaining accurate measurement systems are ever more necessary for the planning and establishing of an applied laboratory concerning measurement equipments and devices and accurate instruments.Important applications of optical electronics, Laser and Optic, under our study include rangefinding and speedometer, aiming through laser, leader and tracker electro optic systems, electro optic discovery and detector systems and more.3. Quatronics laboratory: One of the basic applications of spintronics is quantum communication, the goal of which is to transfer quantum states from one point to the other. Because this is a new branch of the sciences, it is possible to achieve progress and innovation along with developed countries by attending and providing necessary facilities to researchers. This technology is critical to communication safety and quantum communication safety, which will be possible in the near future. Using quantum communication in national sensitive applications will help these sections greatly. Subjects like production of entangled photons, transferring them to receiver and transmitter stations, investigation of environmental effects on entangled photon pairs, design and fabrication parametric reducer convertors, quantum encoding, quantum key distribution, designing and testing quantum gates, entanglement exchange and distillation, investigation of optical fiber effects on entangled photon pairs, and processing quantum information and so on can be performed in this lab.2- Research center members: In 2013, two department faculty members, four Ph.D. students, six M.Sc. students have had the following activities: Num.
