Breaking the Wiedemann-Franz limit in thermoelectrics via separated flat bands
Illia Serhiienko, Fabian Garmroudi, Stefan Enzner +3
Controlling the charge and spin degrees of freedom of electrons in solids has been at the heart of condensed-matter science for centuries. One hallmark of metallic conduction is th…
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…
Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
Dongjin Oh, Stefan Enzner, Lennart Klebl +12
The kagome superconductor family AV3Sb5 (A=Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various…
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…
Van-Hove tuning of Fermi surface instabilities through compensated metallicity
Hendrik Hohmann, Matteo Dürrnagel, Matthew Bunney +6
Van-Hove (vH) singularities in the vicinity of the Fermi level facilitate the emergence of electronically mediated Fermi surface instabilities. This is because they provide a momen…
Observation of termination-dependent topological connectivity in a magnetic Weyl kagome-lattice
Federico Mazzola, Stefan Enzner, Philipp Eck +20
Engineering surfaces and interfaces of materials promises great potential in the field of heterostructures and quantum matter designer, with the opportunity of driving new many-bod…
Flat band separation and robust spin-Berry curvature in bilayer kagome metals
Domenico Di Sante, Chiara Bigi, Philipp Eck +16
Kagome materials have emerged as a setting for emergent electronic phenomena that encompass different aspects of symmetry and topology. It is debated whether the XVSn kagom…
Stabilizing an atomically thin quantum spin Hall insulator at ambient conditions: Graphene-intercalation of indenene
Cedric Schmitt, Jonas Erhardt, Philipp Eck +11
Atomic monolayers on semiconductor surfaces represent a new class of functional quantum materials at the ultimate two-dimensional limit, ranging from superconductors [1, 2] to Mott…
Dynamics and Resilience of the Charge Density Wave in a bilayer kagome metal
Manuel Tuniz, Armando Consiglio, Denny Puntel +22
Long-range electronic order descending from a metallic parent state constitutes a rich playground to study the intricate interplay of structural and electronic degrees of freedom.…
Moiré pattern formation in epitaxial growth on a covalent substrate: Sb on InSb(111)A
Bing Liu, Tim Wagner, Stefan Enzner +4
Structural moiré superstructures arising from two competing lattices may lead to unexpected electronic behavior, such as superconductivity or Mottness. Most investigated moiré hete…
