Electronic properties of twisted multilayer graphene
V. Hung Nguyen, Trinh X. Hoang, J. -C. Charlier
Twisted bilayer graphene displays many fascinating properties that can be tuned by varying the relative angle (also called twist angle) between its monolayers. As a remarkable feat…
Electronic localization in small-angle twisted bilayer graphene
V. Hung Nguyen, D. Paszko, M. Lamparski +3
Close to a magical angle, twisted bilayer graphene (TBLG) systems exhibit isolated flat electronic bands and, accordingly, strong electron localization. TBLGs have hence been ideal…
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…
