Controlling the error mechanism in a tunable-barrier non-adiabatic charge pump by dynamic gate compensation
Frank Hohls, Vyacheslavs Kashcheyevs, Friederike Stein +3
Single-electron pumps based on tunable-barrier quantum dots are the most promising candidates for a direct realization of the unit ampere in the recently revised SI: they are simpl…

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…
