Upstream modes and antidots poison graphene quantum Hall effect
Nicolas Moreau, Boris Brun, Sowmya Somanchi +4
The quantum Hall effect is the seminal example of topological protection, as charge carriers are transmitted through one-dimensional edge channels where backscattering is prohibite…
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…
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…
