Paper Abstract

Layered two-dimensional (2D) materials possess unique optical properties. For example, the monolayer family of Transition Metal Dichalcogenide (TMD) materials (such as WS2 and MoS2) is well known for the existence of a direct band gap. In this talk, we discuss the characterization of the second order nonlinear susceptibility in mono- or few-layer TMDs, which have been recently shown to exhibit extraordinary second harmonic generation. We investigate the large nonlinear response due to resonance enhancement. Theoretical analysis will be discussed and compared with experimental results.
