摘要：

Undoped and tungsten-doped nonstoichiometric vanadium dioxide films have been prepared by a modified sol-gel process, and the effect of synthesis conditions on the parameters of the metal-semiconductor transition in the films has been studied. In particular, it is shown that the temperature of the metal-semiconductor transition in vanadium dioxide decreases with increasing W content and that no phase transition occurs at doping levels above 6 at %. The composition of the films has been evaluated by x-ray diffraction, and their surface morphology has been examined by atomic force microscopy. The parameters of electrical switching in the films can be stabilized by reducing the transition temperature.
