Resonantly-enhanced Raman response in graphene-capped bismuthene on SiC
Lukas Gehrig, Cedric Schmitt, Erica Fragomeni +15
Two-dimensional quantum spin Hall insulators based on atomic monolayers offer a promising route toward dissipationless electronics, yet their practical use is often limited by envi…

Moiré-resonant surface state in ultrathin RuO
Philipp KeÃler, Andreas Feuerpfeil, Armando Consiglio +9
RuO has emerged as a prototypical candidate for altermagnetism. In the face of daunting evidence for magnetic order in the bulk, the focus naturally shifted to surfaces and ult…

Graphene intercalation of the large gap quantum spin Hall insulator bismuthene
Lukas Gehrig, Cedric Schmitt, Jonas Erhardt +5
The quantum spin Hall insulator bismuthene, a two-third monolayer of bismuth on SiC(0001), is distinguished by helical metallic edge states that are protected by a groundbreaking 8…
