Open AccessVacuum level dependent photoluminescence in chemical vapor deposition-grown monolayer MoS 2
The stronger photoluminescence (PL) in chemical vapor deposition (CVD) grown monolayer MoS2 has been attributed to its high crystal quality compared with that in mechanically exfoliated (ME) crystal, which is con...
