Andreev and normal reflections in gapped bilayer graphene-superconductor junctions
Panch Ram, Detlef Beckmann, Romain Danneau +1
We study the Andreev and normal reflection processes -- retro as well as specular -- in a bilayer graphene-superconductor junction where equal and opposite displacement fields are…
Spin-dependent coupling of supercurrent and nonequilibrium quasiparticles in high-field superconductors
P. Maier, D. Beckmann
We report on an experimental investigation of the combined effect of nonequilibrium quasiparticle injection and supercurrent in superconducting aluminum wires. At low temperature,…
Energy distribution controlled ballistic Josephson junction
P. Pandey, D. Beckmann, R. Danneau
We report an experimental study on the tuning of supercurrent in a ballistic graphene-based Josephson junction by applying a control voltage to a transverse normal channel. In this…
Experimental and theoretical study of field-dependent spin splitting at ferromagnetic-insulator-superconductor interfaces
P. Machon, M. J. Wolf, D. Beckmann +1
We present a combined experimental and theoretical work that investigates the magnetic proximity effect at a ferromagnetic-insulator - superconductor (FI-S) interface. The simulati…
A Ballistic Graphene Cooper Pair Splitter
P. Pandey, R. Danneau, D. Beckmann
We report an experimental study of Cooper pair splitting in an encapsulated graphene based multiterminal junction in the ballistic transport regime. Our device consists of two tran…
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…
