Relativistic calculations of photoemission spectra of CoAl(110)

Photoemission spectra obtained from the (110) surface of the ordered CoAl alloy, calculated in the framework of a fully relativistic one-step model of photoemission, are presented. The comparison of the theoretical spectra with experimental results shows good agreement over a wide range of photon en...

Description
Summary:Photoemission spectra obtained from the (110) surface of the ordered CoAl alloy, calculated in the framework of a fully relativistic one-step model of photoemission, are presented. The comparison of the theoretical spectra with experimental results shows good agreement over a wide range of photon energies and emission angles. Additionally we simulate partial disorder by taking into consideration Co antistructure atoms.
