Superconductor spintronics: Modeling spin and charge accumulation in out-of-equilibrium NS junctions subjected to Zeeman magnetic fields
D. Chevallier, M. Trif, C. Dutreix +4
We study the spin and charge accumulation in junctions between a superconductor and a ferromagnet or a normal metal in the presence of a Zeeman magnetic field, when the junction is…
Spin Imbalance and Spin-Charge Separation in a Mesoscopic Superconductor
C. H. L. Quay, D. Chevallier, C. Bena +1
What happens to spin-polarised electrons when they enter a superconductor? Superconductors at equilibrium and at finite temperature contain both paired particles (of opposite spin)…
Flat band and Lifschitz transition in long-range ordered supergraphene obtained by Erbium intercalation
A. Zaarour, V. Malesys, J. Teyssandier +10
Dispersionless energy bands are a peculiar property gathering increasing attention for the emergence of novel photonic, magnetic and electronic properties. Here we report the first…
Symmetry of standing waves generated by a point defect in epitaxial graphene
L. Simon, C. Bena, F. Vonau +4
Using scanning tunneling microscopy (STM) and Fourier Transform STM (FT-STM), we have studied a point defect in an epitaxial graphene sample grown on silicon carbide substrate. Thi…
Quasiparticle Chirality in Epitaxial Graphene Probed at the Nanometer Scale
I. Brihuega, P. Mallet, C. Bena +7
Graphene exhibits unconventional two-dimensional electronic properties resulting from the symmetry of its quasiparticles, which leads to the concepts of pseudospin and electronic c…
Superlattice of resonators on monolayer graphene created by intercalated gold nanoclusters
M. Cranney, F. Vonau, P. B. Pillai +5
Here we report on a "new" type of ordering which allows to modify the electronic structure of a graphene monolayer (ML). We have intercalated small gold clusters between the top mo…
