Abstract

VO2 is a strongly correlated electron system that undergoes a reversible Metal-Insulator transition (MIT) triggered by temperature. The MIT is also coupled with a structural phase transition, from monoclinic insulator to tetragonal metal, therefore, the physical nature of the MIT itself has been long debated to be a Mott-Hubbard and a Peierls transition. In this contribution, VO2 thin films deposited on TiO2(001) have been studied by synchrotron radiation spectrosocopies in order to investigate the strain effect on the MIT properties. The interplay of the lattice, orbital and electron correlation degrees of freedom and their influence on the MIT will be highlighted.
