What is Surface hydrogen densities of variously treated CVD diamond surfaces about?
Hydrogen, deuterium and oxygen densities on diamond 100 surfaces have been investigated by elastic recoil detection Ž . Ž . Ž . analysis ERDA and Rutherford backscattering spectrometry RBS . The 100 surfaces were homoepitaxially grown by Ž . chemical vapor deposition CVD , and surface reactions were enhanced by radical-beam treatments. Atomic force Ž . microscopy AFM was also used for observation of surface topography. AFM images indicate the homoepitaxially grown Ž . diamond 100 surfaces were almost atomically flat surfaces. Hydrogen density of a hydrogen-radical-beam-treated diamond Ž . 15 2 100 surface was about 3 = 10 atomsrcm and was not varied by oxidation with oxygen radical beam. The hydrogen density is about twice as large as that of the ideal hydrogen-terminated 2 = 1 surface. Oxygen density of the oxygen-radicalbeam-treated surface was about F 1 = 10 15 atomsrcm 2 . Either hydrogen-radical-beam or deuterium-radical-beam treatments decreased the hydrogen density. The variations of hydrogen and oxygen densities were discussed in terms of surface structures and roughness.
