Photoluminescence and electrical characterisation of MoS2. a Photoluminescence spectra for the as-grown MoS2 transferred to SiO2 (solid line) vs. mechanically exfoliated monolayer MoS2 (dashed line). b Gate-dependent conductance measurements of a representative unencapsulated MoS2 device. Inset: image of a measured device. Scale bar 1 mm
