ESCA studies of metal-oxygen surfaces using argon and oxygen ion-bombardment
TL;DR: In this paper, a model based on bulk thermodynamic free energy considerations is proposed to explain the sputtering of metal-oxygen surfaces following exposure to Ar + and O 2 + ion bombardment.
Journal ArticleDOI
X-Ray photoelectron spectroscopy of iron–oxygen systems
TL;DR: In this article, it was shown that small perturbations to the energy of the iron (III) 2p electrons can be attributed to changes in crystal structure and multiplet splitting and shake-up in the iron oxides contributes to iron 2p peak widths; the chemisorption of water has a marked effect upon the observed peak profiles; the oxygen 1s peaks due to oxide, hydroxyl, and adsorbed water have been characterised.
