The vibration modes of hydrogen-atom adsorption on the diamond surface were studied with high resolution-electron energy loss spectroscopy. Two main losses were observed at 360 meV and 160 meV. They are assigned to the C-H stretch vibrations and the angle-changing deformation vibrations respectively. Replacing H-atom with D-atom, isotropic shifts were observed in the loss spectra. Heating the diamond surface to 900℃, all of the loss features disappear, but an inelastic continuous loss-structure was observed. Due to H-atom desorp-tion, the dangling-bonds became horizontal bonds on the diamond surface, resulting in the gra-phitization of diamond surface. The appearance of the inelastic continuous loss-structure was the characteristic of graphite π-band. The graphitization of the diamond surface was affirmed further by UPS and AES studies.

用高分辨率电子能量损失谱研究了氢原子吸附在金刚石表面的各种振动模式,其中主要是位于360meV处的C—H键的伸长振动和位于160meV处的“剪”振动。用氚原子代替氢原子吸附在金刚石表面,观测到上述振动模式所发生的同位素位移。将金刚石表面加热至900℃后,各种振动模式全部消失,这时吸附氢原子全部脱去,金刚石表面的悬键变成平躺在表面上,导致金刚石表面石墨化。由于石墨化后π-带的作用,在损失谱上出现一个非弹性的、连续的损失峰结构。我们用UPS和AES技术进一步证实了脱氢后金刚石表面的石墨化。

Electron energy-loss spectroscopy (EELS) has been applied to the analysis of diamond films(DF), diamond-like films (DLC), and graphite. The main energy-loss peaks for DF are thesurface and bulk plasmon energy losses at 23 eV and 34 eV. respectively, and the interband tran-sitions at 5.4 eV. The characteristic energy loss features of DLC are π and (π+σ) electronbulk plasmon energy losses at 4.5 eV and 22.4 eV respectively, and interband transition of13 eV. The energy loss peaks for graphite are the π electron plasmon energy loss at 6 eV, in-terband transition and C-axis plasmon at 13 eV, and energy losses at 20 eV and 25.6 eV causedby C-axis plasmon and plasmon in the basal plane, respectively. The EELS and Raman spec-tram of DLC with H have been compared with that of DLC without H. The ratios of sp~3 tosp~2 carbon sites in DLC both with and without H, and in the second phase DLC of diamondfilms have been calculated according to the π and (π+σ) electron plasmon energy losses.The ratios of the intensity of hω_p (π+σ) loss peak to that of hω_p(σ) loss peak have been usedto estimate the relative content of the second phase DLC in diamond films.
