Abstract:
Adsorbed molecules can significantly affect the properties of atomically thin materials. Physisorbed water plays a significant role in altering the optoelectronic properties of single-layer MoS2 , one such 2D film. Here the distinct quenching effect of adsorbed water on the photoluminescence of single-layer MoS2 is demonstrated through scanning-probe and optical microscopy.
