Emerging Applications of Elemental 2D Materials (Postprint)
Abstract
As elemental main group materials (i.e., silicon and germanium) have dominated the eld of modern electronics, their monolayer 2D analogues have shown great promise for next-generation electronic materials as well as potential game-changing properties for optoelectronics, energy, and beyond. These atomically thin materials composed of single atomic variants of group III through group VI elements on the periodic table have already demonstrated exciting properties such as near-room-temperature topological insulation in bismuthene, extremely high electron mobilities in phosphorene and silicone, and substantial Li-ion storage capability in borophene. Isolation of these materials within the postgraphene era began with silicene in 2010 and quickly progressed to the experimental identication or theoretical prediction of 15 of the 18 main group elements existing as solids at standard pressure and temperatures. This review rst focuses on the signicance of defects/functionali-zation, discussion of different allotropes, and overarching structureproperty relationships of 2D main group elemental materials.
