Indium phosphide photoelectrodes have been studied in situ using surface photovoltage spectroscopy. The observed spectra were a strong function of electrode surface conditions. Electronic properties of the chemically induced surface states correlated well with previously reported values determined by surface photovoltage spectroscopy measurements in vacuum. Metal deposits of Cu and Ag were found to induce deep surface states at 0.9 eV above the valence-band edge.
