Spin- and Angle-resolved Photoelectron Spectroscopy Study of the Quantum Spin Hall Insulator Bismuthene and its Precursor Phase
Niclas Tilgner, Andres David Peña Unigarro, Susanne Wolff +6
Recent studies have revealed that a confined bismuth layer at the graphene/SiC interface can be reversibly switched between a topologically trivial precursor phase and the quantum…

Graphene-capped bismuthene on SiC as a platform for correlated quantum spin Hall edge states
Huu Thoai Ngo, Zamin Mamiyev, Niclas Tilgner +4
Epitaxial bismuthene on SiC(0001) hosts symmetry-protected metallic edge states within a large bulk band gap, establishing it as a promising two-dimensional topological insulator f…
