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…
Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs
Tomas Janda, Joao Godinho, Tomas Ostatnicky +23
Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microsco…
Non-adiabatic quantized charge pumping with tunable-barrier quantum dots: a review of current progress
Bernd Kaestner, Vyacheslavs Kashcheyevs
Precise manipulation of individual charge carriers in nanoelectronic circuits underpins practical applications of their most basic quantum property --- the universality and invaria…
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…
Bilayer Graphene Quantum Dot Defined by Topgates
André Müller, Bernd Kaestner, Frank Hohls +3
We investigate the application of nanoscale topgates on exfoliated bilayer graphene to define quantum dot devices. At temperatures below 500 mK the conductance underneath the groun…
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…
