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…
Direct evidence for efficient carrier multiplication in the topological insulator BiSe
Michael Herb, Leonard Weigl, Niklas Hofman +4
Carrier multiplication (CM), where the absorption of a single photon results in the generation of several electron-hole pairs via impact ionization, plays a pivotal role in the que…
