Abstract

Nonlinear Dispersion Relation and Out-of-Plane Second Harmonic Generation in MoSSe and WSSe Janus Monolayers In article number 2300958, Marko M. Petrić, Sefaattin Tongay, Giancarlo Soavi, Matteo Barbone, and colleagues investigate second and third harmonic generation in MoSSe and WSSe Janus monolayers. They map the full second-order susceptibility tensor, including out-of-plane components, additionally revealing the nonlinear dispersion near exciton resonances. This sets a bedrock for understanding the nonlinear optical properties of Janus transition metal dichalcogenides and probing their use in the next-generation on-chip multifaceted photonic devices.
