Abstract

Superconducting Nb/AlO_x/Nb tunnel junctions have been fabricated on Si membrane windows of only 1.2 μm thickness acting as substrates. The membrane windows with areas between (600 μm)² and (1200 μm)² remained undamaged after the different fabrications steps. The tunnel junctions positioned on the membranes and the bulk silicon substrate have very similar current-voltage characteristics. Using low-temperature scanning electron microscopy the two-dimensional heat diffusion process has been imaged in the detector geometry. This two-dimensional heat diffusion leads to a new cryoelectronic radiation detector concept combining high energy and spatial resolution with a large effective detector area. Applications of this detector concept include soft-x-ray spectroscopy and the nuclear β decay.
