Abstract
The K-edge X-ray absorption near edge spectra (XANES) of P and S in InPS4 s emiconductors is investigated both experimentally and theoretically. Theore tical calculations carried out using high order multiple scattering theory with the ab initio FEFF7 code are found to be in good agreement with experi ment. The notable correspondence between the XANES features for P and S abs orbers allows one to interpret the spectra in terms of strongly mixed free S and P p-states. (C) 2000 Elsevier Science Ltd.
