We have studied about nano-scale surface modification processes induced by slow highly charged ion collisions on highly oriented pyrolytic graphite (HOPG). The diameter of hillock induced by an ion increases with increasing potential energy of incident ions. The shape of induced modifications has changed from a hillock-like to a caldera-like between Bi70+ and Bi75+. In gradient incidence experiments, we observed interesting surface modifications that are asymmetric hillocks and several hillocks induced by an incident ion.

我们研究了高取向热解石墨（HOPG）上缓慢的高电荷离子碰撞引起的纳米级表面改性过程。由离子引起的小丘的直径随着入射离子势能的增加而增加。诱导修饰的形状在 Bi70+ 和 Bi75+ 之间从小丘状变为破火山口状。在梯度入射实验中，我们观察到有趣的表面修饰，这些修饰是不对称的小丘和由入射离子引起的几个小丘。
