           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.
