Webfinding of a bismuthene-type heterostructure, i.e., a mono-layer of Bi deposited on a SiC substrate. With all evidence derived from local spectroscopy, Bi/SiC constitutes a large-gap (∼0.8 eV) QSH insulator. This interpretation has been strongly supported by our successful step-by-step theoreti- Webscale. Bismuthene edges exist at SiC-substrate steps. Differential tunneling conductivity (d I/dV) curves, reflecting the LDOS, have been recorded along a path toward an uphill step …

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]
