Monolayer materials are strongly affected by their potential fluctuations,which are induced by an intrinsic corrugation or the surface roughness of thesubstrate. We compare the effective exciton-exciton annihilation (EEA) rateconstants of monolayer WS2 on substrates with different surface topographies.We show that monolayer WS2 on the substrate with atomically flat terracesdisplays small effective EEA rate constant deviating from the overall tendencyand multiple exciton decay components, which cannot be accounted for by aconventional EEA model. To obtain a correct description, we use a quantized EEAmodel. The intrinsic EEA rate constant for the flat-terrace substratesdetermined by this new model is comparable to that of hBN-encapsulatedmonolayer WS2.
