Abstract
Monolayer WS2 emission is limited by its poor emission directivity. We introduce single hydrogenated amorphous silicon nanospheres (a-Si:H NSs) to realize on-demand directivity modulation. We demonstrate the active control of forward-to-backward modulation ratio via tuning the radius of a-Si:H NSs.
