  Title Snake states in graphene quantum dots in the presence of a p-n junction Type A1 Journal article
  Year (down) 2013 Publication Physical review : B : condensed matter and materials physics Abbreviated Journal Phys Rev B

  Keywords A1 Journal article; Condensed Matter Theory (CMT)  
  Abstract We investigate the magnetic interface states of graphene quantum dots that contain p-n junctions. Within a tight-binding approach, we consider rectangular quantum dots in the presence of a perpendicular magnetic field containing p-n as well as p-n-p and n-p-n junctions. The results show the interplay between the edge states associated with the zigzag terminations of the sample and the snake states that arise at the p-n junction due to the overlap between electron and hole states at the potential interface. Remarkable localized states are found at the crossing of the p-n junction with the zigzag edge having a dumb-bell-shaped electron distribution. The results are presented as a function of the junction parameters and the applied magnetic flux. DOI: 10.1103/PhysRevB.87.035426
