Single-parameter quantized charge pumping in high magnetic fields
B. Kaestner, Ch. Leicht, V. Kashcheyevs +3
We study single-parameter quantized charge pumping via a semiconductor quantum dot in high magnetic fields. The quantum dot is defined between two top gates in an AlGaAs/GaAs heter…
Biased quasi ballistic spin torque magnetization reversal
S. Serrano-Guisan, K. Rott, G. Reiss +3
We explore the fundamental time limit of ultra fast spin torque induced magnetization reversal of a magnetic memory cell. Spin torque precession during a spin torque current pulse…
Robust single-parameter quantized charge pumping
B. Kaestner, V. Kashcheyevs, G. Hein +3
This paper investigates a scheme for quantized charge pumping based on single-parameter modulation. The device was realized in an AlGaAs-GaAs gated nanowire. We find a remarkable r…
Theoretical and experimental investigations of Coulomb blockade in coupled quantum dot systems
F. J. Kaiser, S. Kohler, P. Hänggi +7
Two strongly coupled quantum dots are theoretically and experimentally investigated. In the conductance measurements of a GaAs based low-dimensional system additional features to t…
