Cooperative Effects of Strain and Electron Correlation in Epitaxial VO2 and NbO2

Wei-Cheng Lee, Matthew J. Wahila, Shantanu Mukherjee +9

We investigate the electronic structure of the epitaxial VO${}_2$ films in the rutile phase using the density functional theory combined with the slave spin method (DFT+SS). In DFT-S…
