Edge states and quantum dots in suspended graphene


Periodic conductance oscillations have been observed near quantum Hall plateaus in suspended graphene nanoribbons, attributed to quantum dots that form due to a disorder potential. In a wide flake with two gates, a double-dot system's signature has been observed. Electrostatic confinement is enabled in single-layer graphene due to the gaps between Landau levels, suggesting a way to create gate-defined localized states. Measurements on a test geometry are presented.
