Electric-Field-Induced Second-Harmonic Generation at Charged Interfaces: From Inception to the Eisenthal χ(3) Method and toward Interfacial Electrostatics: A Mini Review

Abstract Electric-field-induced second-harmonic generation (EFISH) has evolved from a fundamental nonlinear optical phenomenon into a powerful approach for probing the electrostatic and structural properties of charged interfaces. This Mini Review traces the historical developmen...
