Long-range spin transport in asymmetric quadruple quantum dots configurations
David Fernández-Fernández, Johannes C. Bayer, Rolf J. Haug +1
We theoretically investigate long-range coherent charge transport in linear quadruple quantum dot (QQD) arrays under reduced symmetry configurations. Employing a master equation ap…
Strongly temperature dependent resistance of meander-patterned graphene
G. Yu. Vasileva, D. Smirnov, Yu. B. Vasilyev +5
We have studied the electronic properties of epitaxial graphene devices patterned in a meander shape with the length up to a few centimeters and the width of few tens of microns. T…
Low-temperature transport properties of a two-dimensional electron gas with additional impurities
E. P. Rugeramigabo, L. Bockhorn, R. J. Haug
We investigate the effect due to background impurities embedded in the region of two-dimensional electron gases to the magnetotransport. These impurities are achieved by homogeneou…
Magnetoresistance Induced by Rare Strong Scatterers in a High Mobility 2DEG
L. Bockhorn, I. V. Gornyi, D. Schuh +3
We observe a strong negative magnetoresistance at non-quantizing magnetic fields in a high-mobility two-dimensional electron gas (2DEG). This strong negative magnetoresistance cons…
Mixing of Edge States at a Bipolar Graphene Junction
H. Schmidt, J. C. Rode, C. Belke +2
An Atomic Force Microscope is used to locally manipulate a single layer graphene sheet. Transport measurements in this region as well as in the unmanipulated part reveal different…
