High quality VO2 thin films synthesized from V2O5 powder for sensitive near-infrared detection

Abstract Vapor transport method has been successfully used to synthesize high quality VO2 thin films on SiO2/Si substrate using V2O5 as a precursor in an inert-gas environment. The morphological and structural evolutions of the intermediate phases during the nucleation and growth processes were inve...
