Abstract
A recent molecular dynamics simulation study on nanoindentation of diamond carried out by Xu has reported observation of the presence of a controversial hexagonal lonsdaleite phase of carbon in the indentation area. In this comment, we question the reported observation and attribute this anomaly to shortcomings of the long range bond order potential (LCBOP) employed in the nanoindentation study.
摘要
徐进行的一项关于金刚石纳米压痕的近期分子动力学模拟研究报告称，在压痕区域观察到了有争议的碳六方纤锌矿相的存在。在本评论中，我们对所报告的观察结果提出质疑，并将这一异常现象归因于纳米压痕研究中所采用的长程键序势（LCBOP）的缺陷。
