Microscopic origin of the bolometric effect in graphene
Roland Jago, Ermin Malic, Florian Wendler
While the thermoelectric and photoconduction effects are crucial in pristine and low-doped graphene, the bolometric effect is known to dominate the photoresponse in biased graphene…
Carrier dynamics in graphene: ultrafast many-particle phenomena
Ermin Malic, Torben Winzer, Florian Wendler +10
Graphene is an ideal material to study fundamental Coulomb- and phonon-induced carrier scattering processes. Its remarkable gapless and linear band structure opens up new carrier r…
Symmetry-breaking supercollisions in Landau-quantized graphene
Florian Wendler, Martin Mittendorff, Jacob C. König-Otto +8
Recent pump-probe experiments performed on graphene in a perpendicular magnetic field have revealed carrier relaxation times ranging from picoseconds to nanoseconds depending on th…
Dark excitons in transition metal dichalcogenides
Ermin Malic, Malte Selig, Maja Feierabend +5
Monolayer transition metal dichalcogenides (TMDs) exhibit a remarkably strong Coulomb interaction that manifests in tightly bound excitons. Due to the complex electronic band struc…
Current enhancement due to field-induced dark carrier multiplication in graphene
Roland Jago, Florian Wendler, Ermin Malic
We present a microscopic study on current generation in graphene in response to an electric field. While scattering is generally considered to reduce the current, we reveal that in…
Review on carrier multiplication in graphene
Ermin Malic, Torben Winzer, Florian Wendler +1
The remarkable gapless and linear band structure of graphene opens up new carrier relaxation channels bridging the valence and the conduction band. These Auger scattering processes…
Proposal for a tunable graphene-based terahertz Landau-level laser
Samuel Brem, Florian Wendler, Ermin Malic
In the presence of strong magnetic fields the electronic bandstructure of graphene drastically changes. The Dirac cone collapses into discrete non-equidistant Landau levels, which…
Carrier multiplication in graphene under Landau quantization
Florian Wendler, Andreas Knorr, Ermin Malic
Carrier multiplication is a many-particle process giving rise to the generation of multiple electron-hole pairs. This process holds the potential to increase the power conversion e…
Population inversion in Landau-quantized graphene
Florian Wendler, Ermin Malic
Landau level lasers have the advantage of tunability of the laser frequency by means of the external magnetic field. The crucial prerequisite of such a laser is a population invers…
