Real-time observation of the intravalley spin-flip process in single-layer WS2

Real-time observation of the intravalley spin-flip process in single-layer WS2

We use helicity-resolved transient absorption spectroscopy to track intravalley scattering dynamics in monolayer WS2. We find that spin-polarized carriers scatter from upper to lower conduction band by reversing their spin orientation on a sub-ps timescale.
