Efficiency of quasiparticle evacuation in superconducting devices



Sukumar Rajauria, L. Pascal, P. Gandit, F. Hekking, B. Pannetier, H. Courtois


We have studied the di®usion of excess quasiparticles in a current-biased superconductor strip in proximity to a metallic trap junction. In particular, we have measured accurately the superconductor temperature at a near-gap injection voltage. By analyzing our data quantitatively, we provide a full description of the spatial distribution of excess quasiparticles in the superconductor. We show that a metallic trap junction contributes signi¯cantly to the evacuation of excess quasiparticles.
