Enhanced Screening in Epitaxial Graphene via Nearly Free-Electron Metal Intercalation
Cedric Schmitt, Lukas Gehrig, Jonas Erhardt +8
Graphene exhibits extraordinarily high carrier mobility, making it a promising platform for next-generation electronics. Scalable growth on SiC, however, suffers from limited diele…
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…
Tunable Electronic Correlations in 135-Kagome Metals
Matteo Crispino, Niklas Witt, Stefan Enzner +4
Kagome metals exhibit rich correlated-electron physics, yet a systematic understanding of the degree of correlation across transition-metal species remains elusive. Using density-f…
Phonon fluctuation diagnostics: Origin of charge order in AVSb kagome metals
Stefan Enzner, Jan Berges, Arne Schobert +7
The microsopic origin of the charge-density wave (CDW) in AVSb (A = K, Rb, Cs) kagome metals remains a longstanding question, often revolving around electron-phonon couplin…
