Giant tunable magnetoresistance of electrically gated graphene ribbon with lateral interface under magnetic field
Quantum dynamics and kinetics of electrically gated graphene ribbons with lateral n–p and n–p–n junctions under magnetic field are investigated. It is shown that the snake-like states [C. W. J. Beenakker, Rev. Mod. Phys. 80, 1337 (2008)] of quasiparticles skipping along the n–p interface do not mani...
