Magnetic confinement of massless Dirac fermions in graphene

De Martino, A., Dell'Anna, L. and Egger, R. (2007). Magnetic confinement of massless Dirac fermions in graphene. Physical Review Letters (PRL), 98(6), doi: 10.1103/PhysRevLett.98.066802

Abstract

Because of Klein tunneling, electrostatic potentials are unable to confine Dirac electrons. We show that it is possible to confine massless Dirac fermions in a monolayer graphene sheet by inhomogeneous magnetic fields. This allows one to design mesoscopic structures in graphene by magnetic barriers, e.g., quantum dots or quantum point contacts.
