Bismuthene on a sic substrate
WebAug 2, 2016 · Bismuthene, a 2D layer of Bi atoms in a honeycomb structure, has recently attracted strong attention because of its record-large nontrivial gap, which is due to the … WebBismuthene, the two-dimensional (2D) allotrope of bismuth, was predicted to be a topological insulator. It was predicted that bismuthene retains its topological phase when grown on silicon carbide in 2015. [40] The prediction was successfully realized and synthesized in 2016. [41]
