The textbook describes the main achievements of the physics of nano-objects, i.e. structures with linear dimensions from 1 nm to 100 nm (1 nm = 10? 9 m). Understanding the methods of obtaining, control, methods of theoretical and experimental study of the structure and physicochemical characteristics of nanoobjects is an integral part of the professional training of specialists in the field of condensed matter physics, theoretical physics and nanotechnology.
