First results of a cryogenic optical photon counting imaging spectrometer using a DROID array
R. A. Hijmering, P. Verhoeve, D. D. E. Martin +3
Context. In this paper we present the first system test in which we demonstrate the concept of using an array of Distributed Read Out Imaging Devices (DROIDs) for optical photon de…
Future optical detectors based on Al superconducting tunnel junctions
G. Brammertz, P. Verhoeve, D. Martin +2
Superconducting tunnel junctions are being developed for application as photon detectors in astronomy. We present the latest results on the development of very high quality, very l…
Optical photon detection in Al Superconducting Tunnel Junctions
G. Brammertz, A. Peacock, P. Verhoeve +2
We report on the successful fabrication of low leakage aluminium superconducting tunnel junctions with very homogeneous and transparent insulating barriers. The junctions were test…
Enhancement of photo-responsivity of small gap, multiple tunnelling superconducting tunnel junctions due to quasiparticle multiplication
G. Brammertz, A. G. Kozorezov, R. den Hartog +5
We recently predicted the formation of a highly non-equilibrium quasiparticle (qp) distribution in low TC multiple tunnelling superconducting tunnel junctions (STJs) [1]. The situa…
Modelling the energy gap in transition metal/aluminium bilayers"
G. Brammertz, A. Golubov, A. Peacock +3
We present an application of the generalised proximity effect theory.
Strong Quasiparticle Trapping In A 6x6 Array Of Vanadium-Aluminum Superconducting Tunnel Junctions
G. Brammertz, A. Peacock, P. Verhoeve +4
A 6x6 array of symmetrical V/Al/AlOx/Al/V Superconducting Tunnel Junctions (STJs) was fabricated. The base electrode is a high quality epitaxial film with a residual resistance rat…
