Observation of non-sinusoidal current-phase relation in graphene Josephson junctions
Christopher English, David Hamilton, Cesar Chialvo +3
We present direct measurements of the current-phase relation for lateral Josephson junctions with a graphene barrier, obtained by a phase-sensitive SQUID interferometry technique.…
Observation of a Snap-Through Instability in Graphene
Scott Scharfenberg, Nikhita Mansukhani, Cesar Chialvo +2
We examine the competition between adhesive and bending energies for few-layered graphene samples placed on rigid, microscale-corrugated substrates. Using atomic force microscopy,…
Probing the mechanical properties of graphene using a corrugated elastic substrate
Scott Scharfenberg, D. Z. Rocklin, Cesar Chialvo +3
The exceptional mechanical properties of graphene have made it attractive for nano-mechanical devices and functional composite materials. Two key aspects of graphene's mechanical b…
Transport Through Andreev Bound States in a Graphene Quantum Dot
Travis Dirks, Taylor L. Hughes, Siddhartha Lal +5
Andreev reflection-where an electron in a normal metal backscatters off a superconductor into a hole-forms the basis of low energy transport through superconducting junctions. Andr…
Magnetoresistance in Single Layer Graphene: Weak Localization and Universal Conductance Fluctuation Studies
Yung-Fu Chen, Myung-Ho Bae, Cesar Chialvo +3
We report measurements of magnetoresistance in single-layer graphene as a function of gate voltage (carrier density) at 250 mK. By examining signatures of weak localization (WL) an…
Negative and Positive Magnetoresistance in Bilayer Graphene: Effects of Weak Localization and Charge Inhomogeneity
Yung-Fu Chen, Myung-Ho Bae, Cesar Chialvo +3
We report measurements of magnetoresistance in bilayer graphene as a function of gate voltage (carrier density) and temperature. We examine multiple contributions to the magnetores…
