Pb-Graphene-Pb josephson junctions: Characterization in magnetic field
Abstract
We fabricate superconductor-graphene-superconductor Josephson junctions with superconducting
regions made of lead (Pb). The critical current through graphene may be modulated
by the external magnetic field; the resulting Fraunhofer interference pattern shows
several periods of oscillations, suggesting that the junction is uniform. Deviations
from the perfect Fraunhofer pattern are observed, and their cause is explained by
a simulation that takes into account the sample design. © 2002-2011 IEEE.
