A quantized current source with mesoscopic feedback
Lukas Fricke, Frank Hohls, Niels Ubbelohde +7
We study a mesoscopic circuit of two quantized current sources, realized by non-adiabatic single- electron pumps connected in series with a small micron-sized island in between. We…

Generation of energy selective excitations in quantum Hall edge states
C. Leicht, P. Mirovsky, B. Kaestner +7
We operate an on-demand source of single electrons in high perpendicular magnetic fields up to 30T, corresponding to a filling factor below 1/3. The device extracts and emits singl…

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…
