Ultrafast photodetection in the quantum wells of single AlGaAs/GaAs-based nanowires
Nadine Erhard, Stefan Zenger, Stefanie Morkötter +8
We investigate the ultrafast optoelectronic properties of single Al0.3Ga0.7As/GaAs-core-shell-nanowires. The nanowires contain GaAs-based quantum wells. For a resonant excitation o…
Ultrafast photocurrents and THz generation in single InAs-nanowires
Nadine Erhard, Paul Seifert, Leonhard Prechtel +5
To clarify the ultrafast temporal interplay of the different photocurrent mechanisms occurring in single InAs-nanowire-based circuits, an on-chip photocurrent pump-probe spectrosco…
Ultrafast helicity control of surface currents in topological insulators with near-unity fidelity
Christoph Kastl, Christoph Karnetzky, Helmut Karl +1
In recent years, a class of solid state materials, called three-dimensional topological insulators, has emerged. In the bulk, a topological insulator behaves like an ordinary insul…
