Title: Doping-controlled Coherent Electron-Phonon Coupling in Vanadium Dioxide

Abstract

Broadband femtosecond transient spectroscopy and density functional calculations reveal that substitutional tungsten doping of a VO 2 film changes the coherent phonon response compared to the undoped film due to altered electronic and structural dynamics.
