S. Ranjan et al., EFFECTS OF INTRINSIC INELASTIC-SCATTERING ON THE CRITICAL-CURRENT OF A JOSEPHSON-JUNCTION, Europhysics letters, 39(3), 1997, pp. 317-321
It is shown that inelastic scattering suffered by tunneling electrons
in the barrier of an S-I-S Josephson junction can lead to a remarkable
nonmonotonic temperature dependence of the critical current of the st
ructure. The understanding of this effect rests on the fact that under
suitable conditions the inevitable loss of coherence can be more than
compensated by a temperature-dependent exponential enhancement of the
pair tunneling probability.
