Plasmonic Metasurface-Enhanced Linear and Nonlinear Processes in Two-Dimensional Semiconductors

It is well known that the optical excitation of two-dimensional (2D) semiconductor monolayers is based on excitons due to remarkably large exciton binding energy in monolayer transition metal dichalcogenides (TMDCs). Therefore, the realization of hybrid 2D TMDC-plasmonic metasurface systems lies in the ability to precisely control and manipulate the light-matter interactions, especially those between surface plasmons and excitons. In this talk, I will focus on the emerging applications of plasmonic metasurfaces with precisely engineered optical properties using monolayer TMDCs as the linear and nonlinear optical media.
