Mesoscopic Diffusion Thermopower in Two-Dimensional Electron Gases
Stephan Rojek, Jürgen König
The diffusion of energy that is locally deposited into two-dimensional electron gases by Joule heating generates transverse voltages across devices with broken symmetry. For mesosc…
Spin pumping through quantum dots
Stephan Rojek, Michele Governale, Jürgen König
We propose schemes for generating spin currents into a semiconductor by adiabatic or non-adiabatic pumping of electrons through interacting quantum dots. The appeal of such schemes…
Adiabatic pumping through an interacting quantum dot with spin-orbit coupling
Stephan Rojek, Jürgen König, Alexander Shnirman
We study adiabatic pumping through a two-level quantum dot with spin-orbit coupling. Using a diagrammatic real-time approach, we calculate both the pumped charge and spin for a per…
Transverse rectification in density-modulated two-dimensional electron gases
A. Ganczarczyk, S. Rojek, A. Quindeau +7
We demonstrate tunable transverse rectification in a density-modulated two-dimensional electron gas (2DEG). The density modulation is induced by two surface gates, running in paral…
