High-resolution core-level spectroscopy study of the ultrathin aluminum oxide film on NiAl(110)
(2011) In Physical Review B (Condensed Matter and Materials Physics) 83(12).- Abstract
- We have studied the ultrathin aluminum oxide film on NiAl(110) by a combination of high-resolution core-level spectroscopy and density functional theory calculations. Energy-dependent core-level data from the O 1s and Al 2p levels allows for a distinction between oxygen and aluminum atoms residing at the surface or inside the aluminum oxide film. A comparison to calculated core-level binding energies from the recent model by Kresse et al. [Science 308, 1440 (2005)] reveals good agreement with experiment, and the complex spectroscopic signature of the thin Al oxide on NiAl(110) can be explained. Our assignment of a shifted component in the O 1s spectra to oxygen atoms at the surface with a particular Al and oxygen coordination may have... (More)
