摘要：
Highly ordered pyrolitic graphite (HOPG) was bombarded by low-energy (approximately 30 eV) O+ and Ne+ at fluxes in the range of 10(15)-10(16) ions cm-2. The initial erosion of a few monolayers was studied with the aid of scanning tunneling microscopy (STM). Damage consisting of hillocks was observed for both O+ and Ne+, and the damage density increased with dose. O+-bombarded surfaces exhibited partial exfoliation of one to two monoatomic layers (probably as a result of chemical erosion), which was absent for Ne+ bombardment. Surface reconstruction of damaged areas was observed. The present work is the first step in an STM study of the effects of atomic oxygen erosion of graphite/epoxy composites in space.
