Abstract

We report x‐ray photoelectron emission measurements of the ternary chalcopyrite compound CuAlS₂. The measurements include the core electron levels and the valence band density‐of‐states distribution. The structure of the valence band includes the s band located 8.5 eV below the valence band edge, the p band located 3.0 eV below, and the copper d band located 0.7 eV below. Our measurements also indicate a higher degree of hybridization between the d and p bands than was observed in AgGaS₂.
