Theoretical calculations of nonlinear optical calculations of 2D materials

Theoretical calculations of nonlinear optical calculations of 2D materials

One important feature of two dimensional (2D) materials is that they possess an exceptional nonlinear optical (NLO) response to light, with conduc¬tivities that are several orders of magnitude larger than their 3D counterparts. The theoretical descriptions of these NLO responses in crystalline syste...
