Exceptionally large enhancement of InP (110) oxidation rate by cesium catalyst

Abstract
Core level photoemission spectroscopy experiments using synchrotron radiation were performed to study the catalytic role of cesium in the oxidation of InP (110). At room temperature, we found an exceptional increase of the oxidation rate by a factor of 1013 in the presence of one monolayer of cesium on InP (110) surface. The oxide mainly consisted of phosphates as InPO4.
