摘要:
除了石墨烯外,很多主族元素也可以形成类似石墨烯的稳定单层结构,并且具有丰富的物理化学性质及广阔的应用前景.其中在物理学中最引人注目的是理论预言在这些材料中预言存在的二维拓扑物性.单元素类石墨烯二维材料已经经历了十余年的研究进程,目前已经理论发现和实验制备出了若干新型二维拓扑材料,成为当前凝聚态物理和新材料领域重要研究方向之一.在这篇评述中,我们将详细介绍这一领域的研究历程、研究思路,以及最新研究进展,并对其进一步的研究方向做出展望.

Abstract:
Alongside graphene, many main group elements can also have stable monolayer graphene-like structures with rich physical and chemical properties as well as broad applications. Among them, the most shinning point is the theoretical prediction of the existence of the two-dimensional to pological properties in these materials. Elementaltwo-dimensional graphene-like materials have been studied for more than ten years .So far, several novel 2D elemental graphene-like topological materials have been discovered theoretically and fabricated experimentally, becoming one of the most important research areas in the field of condensed matter physics and material sciences. In this review, we will introduce the background, concepts and latest research progress of such 2D topological materials in detail .Finally, we discuss the prospect for the research in this area toward practical quantum spin Hall materials.
Key words:  :two-dimensional material, quantum spin Hall effect, graphene-like, spin-orbit coupling
