Comparative analysis of semiconductor-metal phase transition mechanisms in vanadium oxides (V2O3 and VO2)

Abstract

In this study, phase transformation mechanisms in thin V2O3 and VO2 films are analysed based on experimental data and on the qualitative model for vanadium oxides proposed by the authors of the study. New features of semiconductor-metal phase transformation mechanism revealed in V2O3 are discussed. Characteristics of phase transition process in V2O3 is compared with the features of a similar phase transformation in thin VO2 in detail.
