| Abstract(in English) | We have fabricated Nb, Al-AlOx-Al/Ta/Nb Josephson junctions for use as energy resolving X-ray detectors.The junctions have been designed to raise both creation and collection efficiency of quasiparticles.We have investigated the current-voltage characteristics of the junctions on the Al deposition dependence, and found that the characteristics are strongly dependent on the Al deposition rate during the fabrication.The sub-gap leakage current of those junctions fabricated at higher Al deposition rates exhibit very low leakage current(less than 200nA at a bias voltage of 100μV measured at 0.5K). |
