A quantized current source with mesoscopic feedback
Lukas Fricke, Frank Hohls, Niels Ubbelohde +7
We study a mesoscopic circuit of two quantized current sources, realized by non-adiabatic single- electron pumps connected in series with a small micron-sized island in between. We…
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…
Magneto-Transport Properties of Exfoliated Graphene on GaAs
Mirosław Woszczyna, Miriam Friedemann, Klaus Pierz +2
We studied the magneto-transport properties of graphene prepared by exfoliation on a III V semiconductor substrate. Tuneability of the carrier density of graphene was achieved by u…
