Abstract
Results of photoluminescence (PL) and Raman spectroscopy measurements on the effects of different chemical and thermal treatments on the surface properties of InP are presented. From the Raman spectra, values of the surface potential and depletion width are calculated, which allow values of surface recombination velocity to be extracted from the PL data. The PL data provide unambiguous confirmation of the degradation of the unprotected InP surface at temperatures over 200 degrees C.<>
