Multi-nanolayered VO₂/Sapphire Thin Film via Spinodal Decomposition.

ABSTRACT: Coating of VO₂-based thin film has been extensively studied for fabricating energy-saving smart windows. One of the most efficient ways for fabricating high performance films is to create multi-nanolayered structure. However, it has been highly challenge to make such layers in the VO₂-based films using conventional methods. In this work, a facile two-step approach is established to fabricate multilayered VO₂-TiO₂ thin films. We first deposited the amorphous thin films upon sputtering, and then anneal them to transform the amorphous phase into alternating Ti- and V-rich multilayered nanostructure via a spinodal decomposition mechanism. In particular, we take advantage of different sapphire substrate planes (A-plane (11-20), R-plane (1-102), C-plan
