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

O. A. Aktsipetrov, V. O. Bessonov, A. A. Fedyanin +1

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 $\textit{j}_{max…
