Physics and Chemistry of Electrons and Ions in Condensed Matter

Abstract

XPS has been used to study ~0.2 monolayer equivalence of Mn0 on carbon foil. Relative to “bulk Mn0” (a very thick film of Mn0 on carbon foil), the core levels are shift 0.5 eV to higher binding energy (except for O1s) and the L23M23M45 Auger level is shifted 1.1 eV to lower kinetic energy. The valence band narrows relative to “bulk Mn0” and is shifted to higher binding energy. These changes are analogous to the changes observed for highly dispersėd metals on solid substances.
