Substrate Induced Atomic and Electronic Structures of Borophene, Silicene, and Germanene

摘要

Graphene has brought a storm of discoveries of 2-dimentional (2D) materials with exotic physical properties. To date, some new elemental 2D materials with extraordinary physical properties and applications, such as silicene, germanene, and borophene, have been experimentally grown on metal substrates. However, both atomic and electronic structures of substrate supported 2D materials are drastically different from their freestanding counterparts, due to the substrate-material interactions. Therefore, first-principles calculation is employed to probe such kind of interaction, as well as the substrate induced properties of 2D materials. The goal of this review is to provide a concise review of the works from the authors and collaborators about the recent theoretical advances in properties of silicene, germanene, and borophene on metal substrates. We also give a prospect in this field.
