Spin Symmetry of the Bilayer Graphene Groundstate
Frank Freitag, Markus Weiss, Romain Maurand +2
We show nonlinear transport experiments on clean, suspended bilayer graphene that reveal a gap in the density of states. Looking at the evolution of the gap in magnetic fields of d…
Homogeneity of Bilayer Graphene
Frank Freitag, Markus Weiss, Romain Maurand +2
We present non-linear transport measurements on suspended, current annealed bilayer graphene devices. Using a multi-terminal geometry we demonstrate that devices tend to be inhomog…
Contact resistance dependence of crossed Andreev reflection
A. Kleine, A. Baumgartner, J. Trbovic +1
We show experimentally that in nanometer scaled superconductor/normal metal hybrid devices and in a small window of contact resistances, crossed Andreev reflection (CAR) can domina…
Large oscillating non-local voltage in multi-terminal single wall carbon nanotube devices
G. Gunnarsson, J. Trbovic, C. Schonenberger
We report on the observation of a non-local voltage in a ballistic one-dimensional conductor, realized by a single-wall carbon nanotube with four contacts. The contacts divide the…
