Abstract
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.
