Anisotropy of Second‐Harmonic Generation in SnSe Flakes with Ferroelectric Stacking
Advanced Photonics Research, EarlyView.Giant second‐harmonic generation (SHG) susceptibility, on the order of 1000 pm V−1, in SnSe with ferroelectric stacking is demonstrated by theoretical and experimental methods. SHG microscopy is utilized to study few‐layer ferroelectric SnSe flakes on mica substrates. Stripe‐like features in SHG mapping indicate ferroelectric domains. Strong wavelength‐
