Photoemission evidence for crossover from Peierls-like to Mott-like transition in highly strained VO${}_2$

Abstract

We present a spectroscopic study that reveals that the metal-insulator transition of strained VO${}_2$ thin films may be driven towards a purely electronic transition, which does not rely on the Peierls dimerization, by the application of mechanical strain. Comparison with a moderately strained system, which does involve the lattice, demonstrates the crossover from Peierls- to Mott-like transitions.
