Tunable plasmon-enhanced second-order optical nonlinearity in transition metal dichalcogenide nanotriangles

F. Karimi, S. Soleimanikahnoj, I. Knezevic

The development of nanomaterials with a large nonlinear susceptibility is essential for nonlinear nanophotonics. We show that transition-metal-dichalcogenide (TMD) nanotriangles ha…
