An Auger Electron Spectroscopy (AES) and X-Ray Photoelectron Spectroscopy (XPS) Study of CVD and Natural diamonds

摘要

Diamond is a material with many extreme properties. Diamond materials are expected to find increasing use in optical and electronic applications in which heat is a consideration and as a result, oxidation and phase transformation (graphitization) are a concern. Diamond oxidation and phase transformation are connected phenomena that are not well understood. Research of diamond oxidation has been limited. Of the work that does exist, three technical approaches have emerged. The first is work involving chemisorption of specific oxides on powder diamond surfaces, the second set of work involves primarily one research group fortunate enough to study bulk diamond surface reactivity and the third set of research is thermal decomposition analysis and microstruc-tural characterization of CVD diamond surfaces .
