Single-crystalline monolayer hexagonal WS2 is segmented into alternating triangular domains: sulfur-vacancy (SV)-rich and tungsten-vacancy (WV)-rich domains. The WV-rich domain with deep-trap states reveals an electron-dedoping effect, the electron mobility photoluminescence are lower than those of SV-rich shallow-donor by one order magnitude. vacancy-induced strain doping effects investigated via Raman scanning photoelectron microscopy.
