Observation of a low-binding-energy peak in the 2p core-level photoemission from oxidized Al(111)

Berg, C. ; Raaen, S. ; Borg, A. ; Andersen, J. N. LU ; Lundgren, E. LU and Nyholm, R. LU (1993) In Physical Review B (Condensed Matter) 47(19). p.13063-13066
Abstract

High-resolution photoemission studies of oxidation of the Al(111) surface have been performed. The appearance of a component at lower binding energy than the metallic bulk Al emission in the Al 2p spectrum at oxygen exposures above ∼50 langmuir (1 L = 10-6 Torr s) is argued to be due to Al atoms which do not bond directly to oxygen atoms at the oxide-metal interface. Low-energy electron diffraction initially shows a 1×1 structure, which subsequently fades away at higher oxygen exposures, 400 L.
