| 英文摘要 | The nanostructure and atomic structure ahead of the crack tip of highly oriented pyrolytic graphite has been studied by using scanning tunneling microscopy (STM) and that of mica by using atomic force microscopy (AFM). There are many small voids or vacancy clusters ahead of the crack rip, which can migrate with lime and result in the crack rip propagating because of the interaction force between the STM pinpoint and the sample. The nanostructure and atomic structure of loaded crack tip on (001) surface of mica has been observed by AFM. The results show that there exists a severely distorted region about 10 nm in width ahead of the loaded crack tip, and in this region there are many vacancies and vacancy clusters. Around this region there is an abnormal elastic region about 110 nm in width. |
