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…
Lissajous rocking ratchet
S. Platonov, B. Kästner, H. W. Schumacher +2
Breaking time-reversal symmetry (TRS) in the absence of a net bias can give rise to directed steady-state non-equilibrium transport phenomena such as ratchet effects. Here we prese…
Commensurability resonances in two-dimensional magneto-electric lateral superlattices
J. Schluck, S. Fasbender, T. Heinzel +4
Hybrid lateral superlattices composed of a square array of antidots and a periodic one-dimensional magnetic modulation are prepared in heterostructures. The two…
Epitaxial graphene on SiC: Modification of structural and electron transport properties by substrate pretreatment
Mattias Kruskopf, Klaus Pierz, Stefan Wundrack +8
The electrical transport properties of epitaxial graphene layers are correlated with the SiC surface morphology. In this study we show by atomic force microscopy and Raman measurem…
