Ab Initio Core-Level Shifts in Metallic Alloys
Published online by Cambridge University Press: 10 February 2011
Abstract
Core-level shifts and core-hole screening effects in alloy formation are studied ab initio by constrainedl-density-functional total-energy calculations. For our case study, the ordered intermetallic alloy MgAu, final-state effects are essential to account for the experimental Mg 1s shift, while they are negligible for Au 4f. We explain the differences in the screening by analyzing the calculated charge density response to the core hole perturbation.
