Abstract: X-ray photoelectron and emission spectroscopies have been used to study the electronic structure of Cu-x(As2S3)(1-x) and Cu-x(As2Se3)(1-x) compounds across the range where the amount of Cu in the sample strongly affects the photodarkening (PD). Shifts of the As 3d, S 2p and Se 3d core level energies in Cu-contdning samples indicate Cu bonding to As as well as to the chalcogen atoms. These shifts are largest in the selenide compounds. Low-temperature (similar to 0.4 K) anomalies and vectoral photoinduced effects are found to be much less affected by the Cu addition than is the PD, (C) 2000 Elsevier Science B.V.
