Abstract
Photoemission spectra of all CuInC2VI chalcopyrite compounds are measured at Hel line excitation and of CuInS2 also at excitation with ZrMζ radiation. It is found that the In5s – chalcogen p bonding states shift to lower binding energies with increasing anion mass. The energetic position of the S3s band of CuInS2 is also determined. The experimental results obtained are compared with previous measurements and with theoretical band structure calculations.Keywords
