The charge-imbalance voltage induced in a clean superconductor by a supercurrent density J/sub s/ in the presence of a temperature gradient delT is shown to be V=2..pi..v/sub F/llambda/sup 2/..delta.. (J/sub s/xdelT)/3c/sup 2/k/sub B/T/sup 2/ cosh/sup 2/(..delta../2k/sub B/T) g/sub N/S(1-Z), where v/sub F/, l, and lambda (T) are the Fermi velocity, mean free path, and penetration depth, g/sub N/S is the normalized tunnel conductance of the probe junction, and Z (..delta../T) is a known function. This result agrees well with the experiments of Clarke, Fjordboge, and Lindelof.
