Abstract

Electrons which tunnel from the normal electrode to the superconducting electrode of an SIN tunnel junction ultimately combine to form Cooper pairs. If this occurs close to the tunneling region, the phonons emitted during the combination process may enter the normal electrode and heat it. We compared 6 keV X-ray pulse data from AI/A1203/Cu SIN series pairs having narrow leads with pulse data from identical SIN pairs having very wide leads. We found that quasiparticle diffusion in the wide leads was not sufficient to remove the quasiparticles from the junction region.
