K-Edge XANES Spectra of GaAs and ZnSe

Abstract

X-ray absorption near edge structure (XANES) spectra for crystalline GaAs and ZnSe are measured for each K-edge region. Full multiple scattering calculations are also performed. The information on the charge distribution around the X-ray absorbed atom can be obtained if we compare the experimental XANES spectra with full multiple scattering calculations. In these systems core hole potential is important to analyse the spectra.
