摘要
Optical second harmonic generation (SHG) from well-characterised As/Si systems under UHV conditions has been measured. The azimuthal dependence of the SH signal, combined with dispersion studies using pulsed dye and Ti/sapphire lasers, is used to distinguish surface and bulk contributions. The first absolute values of the SH response from well-characterised Si surfaces are also reported.
