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…

Second-harmonic interferometric spectroscopy of the buried Si(111)-SiO interface
A. A. Fedyanin, T. V. Dolgova, O. A. Aktsipetrov +2
The second-harmonic interferometric spectroscopy (SHIS) which combines both amplitude (intensity) and phase spectra of the second-harmonic (SH) radiation is proposed as a new spect…
