Comparison of the oxidation process in strontium and cerium by ultraviolet photoelectron spectroscopy

摘要

The ultraviolet photoemission technique has been applied to the study of the oxidation of strontium and cerium. It has been found that the photoemission measurement provides a method to determine the oxide growth rate perpendicular to the surface, the composition of the surface, and the stable oxide phases formed during the oxidation process.
