Quantum Hall nano-interferometer in graphene
N. Moreau, B. Brun, S. Somanchi +4
Quantum Hall edge states offer avenues for quasiparticle interferometry, provided that the ratio between phase coherence length and quantum Hall interferometer (QHI) size is large…
Optimizing Dirac fermions quasi-confinement by potential smoothness engineering
Boris Brun, Nicolas Moreau, Sowmya Somanchi +7
With the advent of high mobility encapsulated graphene devices, new electronic components ruled by Dirac fermions optics have been envisioned and realized. The main building blocks…
Observation of the spin-orbit gap in bilayer graphene by one-dimensional ballistic transport
L. Banszerus, B. Frohn, T. Fabian +10
We report on measurements of quantized conductance in gate-defined quantum point contacts in bilayer graphene that allow the observation of subband splittings due to spin-orbit cou…
Imaging Dirac fermions flow through a circular Veselago lens
Boris Brun, Nicolas Moreau, Sowmya Somanchi +6
Graphene charge carriers behave as relativistic massless fermions, thereby exhibiting a variety of counter-intuitive behaviors. In particular, at p-n junctions, they behave as phot…
From diffusive to ballistic transport in etched graphene constrictions and nanoribbons
Sowmya Somanchi, Bernat Terrés, Julian Peiro +5
Graphene nanoribbons and constrictions are envisaged as fundamental components of future carbon-based nanoelectronic and spintronic devices. At nanoscale, electronic effects in the…
