ScholarBank@NUS Repository. https://doi.org/10.1063/1.4906880||Abstract:||We demonstrate the growth of high quality single phase films of VO2(A, B, and M) on SrTiO3 substrate by controlling the vanadium arrival rate (laser frequency) and oxidation of the V atoms. A phase diagram has been developed (oxygen pressure versus laser frequency) for various phases of VO2 and their electronic properties are investigated. VO2(A) phase is insulating VO2(B) phase is semi-metallic, and VO2(M) phase exhibits a metal-insulator transition, corroborated by photo-electron spectroscopic studies. The ability to control the growth of various polymorphs opens up the possibility for novel (hetero)structures promising new device functionalities. © 2015 Author(s).||Source Title:||APL Materials||URI:||https://scholarbank.nus.edu.sg/handle/10635/176151||ISSN:||2166-532X||DOI:||10.1063/1.4906880|
