Experimental realization of the minimal two-dimensional multi-orbital kagome model
Bing Liu, Arka Bandyopadhyay, Manish Verma +11
Kagome materials have emerged as a major platform for correlated and topological quantum matter, hosting flat bands, Dirac dispersions and van Hove singularities rooted in frustrat…

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…
