Ag and Cu interfaces with chemically prepared CdS surfaces have been studied under hydrostatic pressures to 10 kbar. These interfaces exhibit a photovoltaic spectrum at photon energies less than Eg due to the existence of new states bound at the interface. We find that the pressure coefficient of the interface-state subband is sensitive to the preparation of the interface even through the atmospheric pressure photovoltaic spectra of the various interfaces studies are very similar.
