Influence of Supercurrents on Low-Temperature Thermopower in Mesoscopic N/S Structures
arXiv:cond-mat/0609309 · doi:10.1007/s10909-006-9257-x
Abstract
The thermopower of mesoscopic normal metal/superconductor structures has been measured at low temperatures. Effect of supercurrent present in normal part of the structure was studied in two cases: when it was created by applied external magnetic field and when it was applied directly using extra superconducting electrodes. Temperature and magnetic field dependencies of thermopower are compared to the numerical simulations based on the quasiclassical theory of the superconducting proximity effect.
