ABSTRACT
We show that thermal activation of quasiparticles from local traps is responsible for the temperature variation of responsivity observed for some superconducting tunneling junction photon detectors. With this model, the depth of the local traps in two different proximized Ta structures was found to be the same, 0.20±0.02 meV. © 2001 American Institute of Physics.

    One of the factors that limits the energy resolution of superconducting tunnel junctions (STJs) as photon detectors is the spatial dependence of the response on the photoabsorption site. To assess the role of spatial inhomogeneities, we have analyzed quasiparticle (qp) diffusion processes in...

    In previous work using thin superconducting films as photon detectors it has been assumed implicitly that the quasiparticle yield in proximized superconducting bilayers should be the same as for a pure superconducting layer with the same energy gap. The reasoning is that, following the energy...
