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…
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…
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…
Quantitative measurement of the magnetic moment of an individual magnetic nanoparticle by magnetic force microscopy
Kai-Felix Braun, Sibylle Sievers, Dietmar Eberbeck +4
We demonstrate the quantitative measurement of the magnetization of individual magnetic nanoparticles (MNP) using a magnetic force microscope (MFM). The quantitative measurement is…
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…
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…
