A complex character of the mechanism of thermal phase transformations from the insulating phase to the metallic phase has been revealed in thin V2O3 films. The insulator–metal phase transition in V2O3 is shown to consist of two stages: the hysteresis-less temperature-extended electron Mott transition extended in temperature and the stepwise structural Peierls transition with temperature hysteresis. The features of the insulator–metal phase transition revealed for V2O3 are discussed. These features are analyzed on the base of their comparison with characteristic features of analogous phase transition in VO2 films.
