Instantaneous band gap collapse in photoexcited monoclinic VO due to photocarrier doping

Daniel Wegkamp, Marc Herzog, Lede Xian +8

Using femtosecond time-resolved photoelectron spectroscopy we demonstrate that photoexcitation transforms monoclinic VO quasi-instantaneously into a metal. Thereby, we exclude…
