The report synthesizes thin films of vanadium dioxide by magnetron sputtering and investigates their structural and electrophysical properties. The possibility of improving the thermochromic properties of VO2 films during their two-stage formation is shown: sequential spraying at a substrate temperature of 2000C and subsequent thermal annealing. It is established that with the increase in the number of successively sprayed layers there is an increase in the film thickness, a change in the shape of the crystal grains, their size and size distribution. The influence of the structure and thickness of VO2 films on the parameters of the phase transition: height, half-width and symmetry of the hysteresis loop is studied.
Based on the obtained experimental results, develop model ideas about the nature of nanoscale fractal transformations in strongly correlated thin-film systems.
