Zero external magnetic field quantum standard of resistance at the 10-9 level
D. K. Patel, K. M. Fijalkowski, M. Kruskopf +10
The quantum anomalous Hall effect holds promise as a disruptive innovation in condensed matter physics and metrology, as it gives access to Hall resistance quantization in terms of…
Zero-field quantum anomalous Hall metrology as a step towards a universal quantum standard unit system
Martin Goetz, Kajetan M. Fijalkowski, Eckart Pesel +9
In the quantum anomalous Hall effect, the edge states of a ferromagnetically doped topological insulator exhibit quantized Hall resistance and dissipationless transport at zero mag…
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…
Precision quantization of Hall resistance in transferred graphene
Mirosław Woszczyna, Miriam Friedemann, Martin Götz +4
We show that quantum resistance standards made of transferred graphene reach the uncertainty of semiconductor devices, the current reference system in metrology. A large graphene d…
