A self-referenced single-electron quantized-current source
Lukas Fricke, Michael Wulf, Bernd Kaestner +8
With the anticipated redefinition of the international system of units (SI) the base units will be linked to fundamental constants of nature [1]. As for the electrical base unit "A…
Towards quantized current arbitrary waveform synthesis
P. Mirovsky, L. Fricke, F. Hohls +5
The generation of ac modulated quantized current waveforms using a semiconductor non-adiabatic single electron pump is demonstrated. In standard operation the single electron pump…
Counting statistics for electron capture in a dynamic quantum dot
Lukas Fricke, Michael Wulf, Bernd Kaestner +10
We report non-invasive single-charge detection of the full probability distribution of the initialization of a quantum dot with electrons for rapid decoupling from an ele…
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…
Synchronized single electron emission from dynamical quantum dots
P. Mirovsky, B. Kaestner, C. Leicht +4
We study synchronized quantized charge pumping through several dynamical quantum dots (QDs) driven by a single time modulated gate signal. We show that the main obstacle for synchr…
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…
