Fluctuation Conductivity in Mesoscopic Superconductor - Normal Metal Contacts

Abstract

The fluctuation conduction of NSN and SNS contacts above T_c are analyzed. For NSN contacts, both Aslamazov-Larkin and Maki- Thompson corrections to the conduction are found to be of the same order and diverge for T_c^* < T_c according to the law (T - T_c^*)^-1. For SNS contacts, the Aslamazov - Larkin correction vanishes,while the Maki - Thompson correction is essential for contacts shorter than the phase-breaking length.
