Position-dependent valley polarization and valley coherence of WS2 monolayers

Not Accessible

Your library or personal account may give you access

Abstract

We characterize the polarization properties of the photoluminescence from CVD-grown WS2 monolayer flakes. We find an inverse relationship between the non-uniform WS2 photoluminescence intensity, the valley polarization and the valley coherence.
