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 MoS_2, one such 2D film. Here we demonstrate the distinct quenching effect of adsorbed water on the photoluminescence of single-layer MoS_2 through scanning-probe and optical microscopies.
