Roles of TiO2 buffer layer for preparation of high performance VO2 thin films with Monoclinic polymorph

Publication date: Available online 18 July 2018Source: Results in PhysicsAuthor(s): Cong Zhang, Chaoyang Kang, Haitao Zong, Shanshan Liang, Chenchen Geng, Ming LiAbstractVanadium dioxide (VO2) thin films with pure Monoclinic phase could be transformed from B-phase by inserting TiO2 buffer layers on transparent amorphous glass substrates at the low temperature of 400°C.This crystalline transformation might be ascribed to oxygen-deficient environment induced by the TiO2 buffer layer and the template effect of TiO2 layer for M-VO2 phase. The simplicity in phase regulation of the present method and the superior optical and electrical properties of the films may allow its wide applications in thermo-opto-electro sensing devices.
