Strong near band-edge excited second-harmonic generation from multilayer 2H Tin diselenide
We report strong second-harmonic generation (SHG) from 2H polytype of multilayer Tin diselenide (SnSe(2)) for fundamental excitation close to the indirect band-edge in the absence of excitonic resonances. Comparison of SHG and Raman spectra from exfoliated SnSe(2) flakes of different polytypes shows...
