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. |
