Validation of a quantized-current source with 0.2 ppm uncertainty
Friederike Stein, Dietmar Drung, Lukas Fricke +11
We report on high-accuracy measurements of quantized current, sourced by a tunable-barrier single-electron pump at frequencies up to GHz. The measurements were performed wi…
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…
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…
Integrated quantized electronics: a semiconductor quantized voltage source
Frank Hohls, Armin C. Welker, Christoph Leicht +7
The Josephson effect in superconductors links a quantized output voltage Vout = f \cdot(h/2e) to the natural constants of the electron's charge e, Planck's constant h, and to an ex…
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…
