Influence of Metal Oxide Interface Layers on the Thermochromic Properties of VO2 Thin Films Deposited by Magnetron Sputtering

Advanced Materials Interfaces, EarlyView.
This study investigates the thermochromic properties of VO2 deposited on aluminum doped zinc oxide precoated fused silica with Al2O3, TiO2, and WO3 as interface layers. The results indicate that the metal‐to‐insulator transition is highly influenced by the grains formed at the interface.
