Our research focuses on transport in nanoscale and mesoscopic systems—particularly carbon nanotubes (CNTs), graphene, nanostructured superconductors, and topological insulators. These systems often exhibit new properties due to confinement and strong electron correlations. Improved understanding of such systems has ramifications for subjects from high-temperature superconductivity to quantum computing. Our experiments connect unique materials, nanoscale structures, and electron correlations to novel fabrication and low-temperature measurements. Major current research thrusts include studying 1) electron interactions in CNTs, 2) superconducting proximity effects in CNTs, graphene, and Nb/Au nanopatterned bilayers, 3) tunneling spectroscopy of graphene and CNTs, and 4) electromechanical behavior of graphene.
