摘要
原子层厚度的二维材料所展示的许多特性,为基础研究和应用提供了多种可能.本文介绍了二维材料在自旋电子学、能谷电子学以及光学等领域的研究进展.采用第一性原理方法通过计算发现,吸附分子、引入掺杂和缺陷、加入应变及外场、搭建异质结等可对二维材料性质进行有效调控,这为基于二维材料的新型纳米器件的设计制备提供了有力的支持.
Many properties exhibited by two-dimensional(2D)materials with atomic layer thickness provide multiple possibilities for basic research and applications.In this paper,progress on spintronics,valleytronics,and optics of 2D materials are introduced.Based on the first-principles calculations,it is found that molecular adsorption,doping,defects,strain forces,external fields,and formation of heterostructures can efficiently tune the properties of 2D materials,which is helpful for the application of 2D materials on novelty nanodevices.
