Emission of Geometrically Modulated Monolayer Semiconductors

ORAL

Abstract

Emission, including light and electrons, of the monolayer 2D lattices offers significant scientific interests in materials sciences and potential optoelectronics applications.
However, monolayers of transition metal dichalcogenides (TMDs) exhibit reduced efficiency on optical emission and electron field emission. Here, emission of the geometrically modulated monolayer semiconductors suspended with 1D nanoarrays is demonstrated. Synthesized TMD monolayers offer an ideal platform to explore the fundamental process of the emission of the TMD. Geometrical modulation and charge transfer of the semiconducting monolayers can be significantly tuned with the structural suspension with nanoarrays.
