Abstract(in English) | We have fabricated Josephson junctions with Al, Ta/Nb structure for X-ray detection.We have selected a Ta layer to be absorber for quasiparticles generated by an incident X-ray to the junction because of having a long life time of quasiparticles and a high absorption efficiency for X-ray.A Nb layer has served as not only the barrier for quasiparticle rejection,but also the buffer layer for making a body cubic centered Ta layer.An Al layer has been selected for not only the formation of AlOx barrier,but also the trapping layer of quasiparticles.Fabricated junctions have shown excellent current-voltage characteristics at 0.4 K. |
