The goal of this course is studying basic semiconductor and nanotechnology methods, which are the most suitable for designs and production of nanoelectronics, optoelectronics and other quantum-dimensional devices.
In the first course part changes of electrical, physical and optical properties of bulk materials during their growing as low-dimensional structures (quantum wells, wires and dots) due to effects of dimensional quantization are studied. The main attention is devoted to such materials as C, Si, compounds and solid solutions GexSi1-x, АIIВVI and AIIIBV.
In the second course part principal technologies of quantum-dimensional structures growth and processing are considered: liquid-phase epitaxy (LPE), molecular beam epitaxy (MBE), metal organic vapor deposition (MOCVD), nanolithography, self-assembling quantum wires and dots.
In the last course part the most impressive examples and results of using low-dimensional inorganic semiconductor structures in micro- and nanoelectronics are considered. Such devices as infrared, visible and ultraviolet radiation emitting diodes and lasers, photodetectors and transistors are selected for this purpose.
