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…
Superconducting Tunneling Spectroscopy of a Carbon Nanotube Quantum Dot
Travis Dirks, Yung-Fu Chen, Norman O. Birge +1
We report results on superconducting tunneling spectroscopy of a carbon nanotube quantum dot. Using a three-probe technique that includes a superconducting tunnel probe, we map out…
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…
Non-equilibrium Tunneling Spectroscopy in Carbon Nanotubes
Yung-Fu Chen, Travis Dirks, Gassem Al-Zoubi +2
We report measurements of the non-equilibrium electron energy distribution in carbon nanotubes. Using tunneling spectroscopy via a superconducting probe, we study the shape of the…
