Extraordinary Second Harmonic Generation in Tungsten Disulfide Monolayers

We investigate Second Harmonic Generation (SHG) in monolayer WS(2) both deposited on a SiO(2)/Si substrate or suspended using transmission electron microscopy grids. We find unusually large second order nonlinear susceptibility, with an estimated value of d(eff) ~ 4.5 nm/V nearly three orders of mag...
