Silicene: a review of recent experimental and theoretical investigations
TLDR
The structural, electronic and vibrational properties of free-standing silicene, as predicted from first-principles calculations are discussed, providing insights into the different phases or atomic arrangements ofsilicene observed on this metallic surface, as well as on its electronic structure.Abstract:
Silicene is the silicon counterpart of graphene, i.e. it consists in a single layer of Si atoms with a hexagonal arrangement. We present a review of recent theoretical and experimental works on this novel two dimensional material. We discuss first the structural, electronic and vibrational properties of free-standing silicene, as predicted from first-principles calculations. We next review theoretical studies on the interaction of silicene with different substrates. The growth and experimental characterization of silicene on Ag(1 1 1) is next discussed, providing insights into the different phases or atomic arrangements of silicene observed on this metallic surface, as well as on its electronic structure. Recent experimental findings about the likely formation of hexagonal Si nanosheets on MoS2 are also highlighted.read more
