基于第四主族的类石墨烯二维材料最新进展:制备,性能和相关应用

Recent Progress of Group-IVA-Based 2D Materials Beyond Graphene: Fabrication,Properties and Related Applications

在类石墨烯时代,蜂窝状晶格排列的第四主族单层原子晶体(包括硅烯,锗烯,锡烯和铅烯)引起了广泛的关注。它们具有各种优异的特性,包括高载流子迁移率,线性色散能带和量子自旋霍尔效应,从而使其易于实现在许多前沿领域的应用。在本文中,作者回顾了基于第四主族二维材料的最新进展,重点研究了在不同基底上的制备,几何和电子特性及其在晶体管,电池,气体传感器等领域的潜在应用。最后,作者还讨论了该领域当前的挑战和机遇,将激发对第四主族二维材料这一前沿领域的更多研究。

In the post-graphene era,single layers of group-IVA atoms arranged in a honeycomb lattice(including silicene,germanene,stanene,and plumbene) have attracted extensive attention.They possess various remarkable properties,including high carrier mobility,linear dispersing energy bands,and quantum spin Hall effects(QSH),facilitating their versatile applications in many frontier fields.In this paper,we review the recent progress of group-IVA-based 2D materials(G4^(2DM)),focusing on the fabrication of G4^(2DM) on different substrates,the geometrical and electronic properties as well as their potential applications in transistors,batteries,gas sensors and so on.Finally,we also discuss the current challenges and opportunities in the G4^(2DM) area,which should inspire more research into this edge-cutting area of 2D materials.
