Direct evidence of interaction-induced Dirac cones in a monolayer silicene/Ag(111) system
Direct evidence of interaction-induced Dirac cones in a monolayer silicene/Ag(111) system
Silicene, analogous to graphene, is a one-atom-thick two-dimensional crystal of silicon which is expected to share many of the remarkable properties of graphene. The buckled honeycomb structure of silicene, along with its enhanced spin-orbit coupling, endows silicene with considerable advantages over graphene in that the spin-split states in silicene are …
