摘要

用多种快重离子辐照高定向石墨（HOPG）

借助扫描隧道显微镜（STM ）系统地研究了表面及体内缺陷。结果表明

离子在表面及解理面上都形成了小丘状的缺陷

且在表面较容易形成

可以用非连续损伤径迹结构来对其进行解释

Abstract

Damage on surface and in bulk of highly oriented pyrolytic graphite (HOPG) induced by variety of heavy ions was studied by scanning tunneling microscopy (STM). Hillocks rather than hollows were observed either on the original sample surfaces or on the cleaved surfaces. Compared to the original surface

the probability of track formation was significantly reduced in the deeper bulk layers. This could be understood by assuming a morphology consisting of a discontinuous sequence of damage segments instead of a homogeneous cylinder.
