Optical and Electrical Properties of V2O5 Gel-Based Thin Films
Abstract
Films of various thicknesses have been produced on silicon substrates via centrifugation of V2O5 gel, followed by vacuum annealing. The optical characteristics of the films have been shown to be well fitted by the Cauchy and Bruggeman models. The thermal hysteresis loop of their insulator–metal transition and the amplitude of the variation in their resistivity are determined by their phase composition and the degree of their crystallinity.
