Abstract

Two-dimensional (2D) layered molybdenum disulfide (MoS₂) has become a very promising candidate semiconducting material for future optoelectronic devices, owing to its unique properties. However, monolayer MoS₂ is still a weak photon emitter, compared with other direct band gap semiconductors, which requires extra techniques or complicated steps to enhance its photon emission efficiency. Here, we demonstrated that nanostructured monolayer MoS₂, produced by one-step chemical vapor deposition (CVD) growth, shows highly enhanced PL emission. The effective enhancement factor could be up to ∼43. Our results open the door to manipulating the optical properties of future devices by using nanostructured 2D monolayers.
