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…
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…
Non-equilibrium carrier dynamics and band structure of graphene on 2D tin
Maria-Elisabeth Federl, Niklas Witt, Biao Yang +9
Intercalation of epitaxial graphene on SiC(0001) with Sn results in a well-ordered Sn structure on the SiC surface with quasi-freestanding graphene on top. While the e…
