Low-temperature proximity effect in clean metals with repulsive electron-electron interaction

“…19,20 The clean case has been studied for a hypothetic normal metal with no interaction between electrons, 21,22 and for a "normal" metal with a weak attractive interaction and reduced critical temperature. 8,23,24 Reference 24 numerically calculated a decay of the order parameter also in a single particular case of a repulsive interaction at finite temperatures. An exponential decay of ⌬͑x͒ ϰ exp͑−x / ͒, as a function of the distance x from the SN boundary, has been found with the proximity length ϰ 1 / T in the clean limit, and ϰ 1 / ͱ T in the dirty limit.…”
