Abstract

Soft x-ray spectroscopy is used to investigate the strain dependence of the metal-insulator transition of VO ₂. Changes in the strength of the V3d-O2p hybridization are observed across the transition and are linked to the structural distortion. Furthermore, although the V-V dimerization is well described by dynamical mean-field theory, the V-O hybridization is found to have an unexpectedly strong dependence on strain that is not predicted by band theory, emphasizing the relevance of the O ion to the physics of VO ₂.
