Phys. Rev. Lett. 91, 057005 (2003) [4 pages]Multiple Andreev Reflections in a Carbon Nanotube Quantum DotReceived 9 April 2003; published 1 August 2003 We report resonant multiple Andreev reflections in a multiwall carbon nanotube quantum dot coupled to superconducting leads. The position and magnitude of the subharmonic gap structure is found to depend strongly on the level positions of the single-electron states which are adjusted with a gate electrode. We discuss a theoretical model of the device and compare the calculated differential conductance with the experimental data. © 2003 The American Physical Society URL:
