Ferroelectricity and Nonlinear Optical Responses in Two-Dimensional Distorted MX2Y (M = Cu, Ag, Au; X = Chalcogens; Y = Halogen) Monolayers

Two-dimensional (2D) materials with spontaneous polarization can exhibit large second-order nonlinear optical (NLO) effects. Here, we present a series of stable distorted MX2Y monolayers by using first-principles calculations and lattice vibration analysis. The structural distortion leads to a lower...
