Ultrafast signatures of Dirac / flat-band hybrid states from time-resolved ARPES
Maria-Elisabeth Federl, Johannes Gradl, Franziska Bergmeier +12
Hybridization of highly itinerant Dirac electrons with localized flat-band states is predicted to yield emergent phenomena such as exotic heavy-fermion behaviour. Epitaxial graphen…
Influence of twist angle on ultrafast charge separation in WS2-graphene heterostructures
Niklas Hofmann, Leonard Weigl, Johannes Gradl +4
Van der Waals (vdW) heterostructures, formed by stacking two-dimensional materials, offer highly tunable electronic and optical properties, with the twist angle between layers acti…
Rubidium intercalation in epitaxial monolayer graphene
Letizia Ferbel, Stefano Veronesi, Tevfik Onur Mentes +7
Alkali metal intercalation of graphene layers has been of particular interest due to potential applications in electronics, energy storage, and catalysis. Rubidium (Rb) is one of t…
k-resolved ultrafast light-induced band renormalization in monolayer WS on graphene
Niklas Hofmann, Alexander Steinhoff, Razvan Krause +6
Understanding and controlling the electronic properties of two-dimensional materials is crucial for their potential applications in nano- and optoelectronics. Monolayer transition…
Quasi-free Standing Epitaxial Graphene on SiC by Hydrogen Intercalation
C. Riedl, C. Coletti, T. Iwasaki +2
Quasi-free standing epitaxial graphene is obtained on SiC(0001) by hydrogen intercalation. The hydrogen moves between the 6root3 reconstructed initial carbon layer and the SiC subs…
