Magnetic confinement of massless Dirac fermions in graphene

De Martino, A., Dell'Anna, L. & Egger, R. (2007). Magnetic confinement of massless Dirac fermions in graphene. Physical Review Letters (PRL), 98(6), article number 066802. 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.
