Recent progress in 2D group-V elemental monolayers:fabrications and properties

摘要

A large number of two-dimensional(2D)monoelemental materials with huge application potentials have been developed,since graphene was reported as a monoelemental material with unique properties.As cousins of graphene,2D group-V elemental monolayers have gained tremendous interest due to their electronic properties with significant fundamental bandgap.In this review,we extensively summarize the latest theoretical and experimental progress in group-V monoelemental materials,including the latest fabrication methods,the properties and potential applications of these 2D monoelementals.We also give a perspective of the challenges and opportunities of 2D monoelemental group-V monolayer materials and related functional nanodevices.
