Single Wall Carbon Nanotube Weak Links
We have reproducibly contacted gated single wall carbon nanotubes (SWCNT) to
superconducting leads based on niobium. The devices are identified to belong to
two transparency regimes: The Coulomb blockade and the Kondo regime. Clear
signature of the superconducting leads is observed in both regimes and in the
Kondo regime a narrow zero bias peak interpreted as a proximity induced
supercurrent persist in Coulomb blockade diamonds with Kondo resonances.Comment: Proceeding for International Symposium on Mesoscopic
