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…
Influence of sulphur vacancies on ultrafast charge separation in WS-graphene heterostructures
Johannes Gradl, Niklas Hofmann, Leonard Weigl +6
Understanding how defects influence charge separation in WS-graphene heterostructures is crucial for future applications in light harvesting and detection. Previous studies hav…
Influence of doping on non-equilibrium carrier dynamics in graphene
Leonard Weigl, Johannes Gradl, Peter Richter +5
Controlling doping is key to optimizing graphene for high-speed electronic and optoelectronic devices. However, its impact on non-equilibrium carrier lifetimes remains debated. Her…
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…
