We have investigated CuInSe2 surfaces as well as the interfaces of the systems ZnSe/CuInSe2 and ZnS/CuInSe2 by vacuum ultraviolet photoelectron spectroscopy with synchrotron radiation. The CuInSe2 substrates are prepared with a hydrogen plasma and show high quality surfaces suitable for further growth of ZnSe in order to determine the valence-band offset of ZnSe/CuInSe2. At the surface of CuInSe2 Se atoms have been replaced by Te or S atoms, so that CuInTe2 or CuInS2 surfaces were formed. We determined the valence-band offsets of CuInTe2/CuInSe2 and CuInS2/CuInSe2 to be Delta E-vb(CuInTe2/CuInSe2) = (0.85+/-0.05) eV and Delta E-vb(CuInS2/CuInSe2) =(0.87+/-0.05)eV. Delta E-vb(ZnSe/CuInSe2) = -(0.5+/-0.1)eV is in good agreement with values from literature. Furthermore we have examined the interface ZnS/CuInS2 and obtained the valence-band offset Delta E-vb(ZnS/CuInS2)= -(2.3+/-0.1)eV. (C) 1998 American Institute of Physics. [S0021-8979(98)03317-9].
