“…Semiconductors, fabricated at the nanoscale, demonstrate a drastic change in optical and electron properties [5]. These changes are due, above all, to quantum-dimensional effects, associated with the quantization of charge carriers' energy, the motion of which is restricted, in one, two or three directions [6,7]. Properties of the obtained nanostructures depend in turn on the parameters of the starting crystal and the methods of synthesis [8].…”
