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…
Non-thermal nature of photo-induced insulator-to-metal transition in NbO
Rakesh Rana, J. Michael Klopf, Jörg Grenzer +3
We study the photo-induced metallization process in niobium dioxide NbO. This compound undergoes the thermal insulator-to-metal transition at the remarkably high temperature of…
Up to 40 % reduction of the GaAs band gap energy via strain engineering in core/shell nanowires
L. Balaghi, G. Bussone, R. Grifone +7
The great possibilities for strain engineering in core/shell nanowires have been explored as an alternative route to tailor the properties of binary III-V semiconductors without ch…
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…
