Graphene-capped bismuthene on SiC as a platform for correlated quantum spin Hall edge states
Huu Thoai Ngo, Zamin Mamiyev, Niclas Tilgner +4
Epitaxial bismuthene on SiC(0001) hosts symmetry-protected metallic edge states within a large bulk band gap, establishing it as a promising two-dimensional topological insulator f…
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…
Identifying Electronic Doorway States in the Secondary Electron Emission from Layered Materials
Anna Niggas, Maosheng Hao, Peter Richter +11
We investigate the secondary low-energy electron emission induced by inelastic electron scattering from graphene and layered materials thereof. By applying a coincidence detection…
Direct view on the ultrafast carrier dynamics in graphene
Jens Christian Johannsen, Søren Ulstrup, Federico Cilento +11
The ultrafast dynamics of excited carriers in graphene is closely linked to the Dirac spectrum and plays a central role for many electronic and optoelectronic applications. Harvest…
Localized states influence spin transport in epitaxial graphene
T. Maassen, J. J. van den Berg, E. H. Huisman +4
We developed a spin transport model for a diffusive channel with coupled localized states that result in an effective increase of spin precession frequencies and a reduction of spi…
