A Study of the Growth Interfaces of Diamond under High Temperature and High Pressure
-
摘要: 利用扫描电镜及Auger电子谱技术研究了高温高压下金刚石单晶生长界面的特性，观察到了金刚石单晶表面及金属膜表面的沟槽结构及金刚石-金属、金属-石墨两个主界面间的过渡层结构及界面间C原子电子组态的变化。Abstract: The growth interface of diamond crystal and the catalytic alloy film graphite interface were measured by using a scanning electron microscope and Auger scanning microprobe. The groove structures on the catalytic alloy film surface, the diamond surface and the transition layer have been observed. There exist marked differences in the shapes and relative energies of Auger spectra of carbon atom. The changes in line-shapes and relative energies of these Auger line definitely reflect the differences in the wave functions of the 2s and 2p electrons in carbon atoms, in graphite and diamond crystal, respectively.
