Anomalous Cyclotron Motion in Graphene Superlattice Cavities
R. Kraft, M. -H. Liu, P. B. Selvasundaram +4
We consider graphene superlattice miniband fermions probed by electronic interferometry in magneto-transport experiments. By decoding the observed Fabry-Pérot interference patterns…
Andreev reflection in ballistic normal metal/graphene/superconductor junctions
P. Pandey, R. Kraft, R. Krupke +2
We report the study of ballistic transport in normal metal/graphene/superconductor junctions in edge-contact geometry. While in the normal state, we have observed Fabry-Pérot reson…
Electrostatic Superlattices on Scaled Graphene Lattices
Szu-Chao Chen, Rainer Kraft, Romain Danneau +2
A scalable tight-binding model is applied for large-scale quantum transport calculations in clean graphene subject to electrostatic superlattice potentials, including two types of…
Valley subband splitting in bilayer graphene quantum point contact
R. Kraft, I. V. Krainov, V. Gall +4
We report a study of one-dimensional subband splitting in a bilayer graphene quantum point contact in which quantized conductance in steps of is clearly defined down to…
