Current-induced break of inversion symmetry in Si: optical second-harmonic generation induced by a dc current

Optics 2007-05-23 v1 General Physics

Abstract

The dc-current-induced optical second-harmonic generation is observed at the surface of centrosymmetric single crystal of Si. Surface dc-current with density up to jmax103\textit{j}_{max} \sim 10^{3} A/cm2^{2} results in break of inversion symmetry of Si and induces optical second-harmonic generation with intensity that corresponds to the appearance of dipole second-order susceptibility χ(2)d(jmax)31015\chi^{(2)d}(j_{max})\sim 3 \cdot 10^{-15}m/V.
