Phys. Rev. B 66, 165411 (2002) [4 pages]Andreev current in finite-size carbon nanotubesReceived 22 June 2002; published 23 October 2002 We investigate the effect of interactions on Andreev current at a normal-superconductor junction when the normal phase is a Luttinger liquid with repulsive interactions. In particular, we study the system of a finite-size carbon nanotube placed between one metallic and one superconducting lead. We show that interactions and finite-size effects give rise to significant deviations from the standard picture of Andreev current at a normal-superconductor junction in the nearly perfect Andreev limit. © 2002 The American Physical Society URL:
