Anisotropy of Second‐Harmonic Generation in SnSe Flakes with Ferroelectric Stacking
Second-Harmonic Generation In their Research Article (10.1002/adpr.202500033), Kung-Hsuan Lin and co-workers show that few-layer SnSe with ferroelectric stacking exhibits second harmonic generation (SHG) efficiencies up to three orders of magnitude higher than conventional nonlinear crystals. The SHG response is highly anisotropic and strongly dependent on the excitation wavelength.
