Geometric interference in a high-mobility graphene annulus p-n junction device
Son T. Le, Albert F. Rigosi, Joseph A. Hagmann +3
The emergence of interference is observed in the resistance of a graphene annulus pn junction device as a result of applying two separate gate voltages. The observed resistance pat…

Strong equilibration of Landau levels edge-states at the graphene edge
Son T. Le, Joseph A. Hagmann, Nikolai Klimov +4
We present the results of an experimental study of the interaction of quantized Landau level (LL) edge-states at the physical edge of graphene by using a graphene pn junction devic…
