二维纳米材料异质结构的原子间相互作用模型(英文)
发布时间:2021-11-13 09:51
近些年二维纳米材料得到大量的研究,其中一个热点研究方向是将不同的二维纳米材料堆垛成纳米异质结构,从而实现多功能的纳米器件.这些二维纳米材料可以从面外和面内两个方向上进行堆垛从而形成两类不同的异质结构.在关于这类二维纳米材料及其异质结构的理论研究中,原子间的相互作用起到类似于连续介质力学中本构关系的作用.因此学者提出了多种方案用于描写原子间相互作用,主要包括第一性原理计算和经验势能模型等.本文主要是对比和分析各种描写二维纳米材料及其异质结构的常见经验势能模型,从而为研究人员选择相互作用模型提供一些参考.
