Sub-gap spectroscopy of thermally excited quasiparticles in a Nb contacted carbon nanotube quantum dot
M. Gaass, S. Pfaller, T. Geiger +4
We present electronic transport measurements of a single wall carbon nanotube quantum dot coupled to Nb superconducting contacts. For temperatures comparable to the superconducting…
Universality of the Kondo effect in quantum dots with ferromagnetic leads
M. Gaass, A. K. Huettel, K. Kang +3
We investigate quantum dots in clean single-wall carbon nanotubes with ferromagnetic PdNi-leads in the Kondo regime. In most odd Coulomb valleys the Kondo resonance exhibits a pron…
Carbon Nanotube Quantum Dots with Nb Contacts
Emiliano Pallecchi, Markus Gaass, Dmitry Ryndyk +1
We report on the preparation of carbon nanotube quantum dots using superconducting electrodes made of niobium. Gate-controllable supercurrents with values of up to 30 nA are induce…
Bistability in superconducting rings containing an inhomogeneous Josephson junction
M. Gaass, S. Nadj-Perge, Z. Radović +4
We investigate the magnetic response of a superconducting Nb ring containing a ferromagnetic PdNi Josephson junction and a tunnel junction in parallel. A doubling of the switching…
