Abstract

A new procedure for deposition of VO2 films on single-crystal sapphire supports from alcoholic solutions under hydrothermal conditions has been proposed. The obtained materials show sharp dielectric–metal transition with change in electrical resistance value up to four orders of magnitude in proximity to critical temperature (68°C). Conditions for the synthesis of films comparable in electrophysical characteristics with analogs prepared in aqueous media have been found. The suggested procedure opens new possibilities for the hydrothermal synthesis of film oxide materials.
