Strain Correlated Linearly Polarized Photoluminescence in WSe2/WS2 Moire Superlattices

Abstract Reliable optical control of valley degrees of freedom in moiré excitons requires that the emitted polarization faithfully reflects the underlying valley state. Here, we show that linearly polarized photoluminescence from WSe2/WS2 moiré excitons is largely insensitive t...
