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…
Moiré-resonant surface state in ultrathin RuO
Philipp Keßler, 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…
Epitaxial RuO and IrO films by pulsed laser deposition on TiO(110)
Philipp Keßler, Tim Waldsauer, Vedran Jovic +5
We present a systematic growth study of epitaxial RuO(110) and IrO(110) on TiO(110) substrates by pulsed laser deposition. We describe the main challenges encountered i…
Absence of magnetic order in RuO: insights from SR spectroscopy and neutron diffraction
Philipp Keßler, Laura Garcia-Gassull, Andreas Suter +8
Altermagnets are a novel class of magnetic materials besides ferro- and antiferromagnets, where the interplay of lattice and spin symmetries produces a magnetic order that is stagg…
