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…
