Heat transfer coefficient saturation in superconducting Nb tunnel junctions contacted to a NbTiN circuit and an Au energy relaxation layer
Stefan Selig, Marc Peter Westig, Karl Jacobs +2
In this paper we present the experimental realization of a Nb tunnel junction connected to a high-gap superconducting NbTiN embedding circuit. We investigate relaxation of nonequil…
A 490 GHz planar circuit balanced Nb-AlO-Nb quasiparticle mixer for radio astronomy: Application to quantitative local oscillator noise determination
M. P. Westig, M. Justen, K. Jacobs +4
This article presents a heterodyne experiment which uses a 380-520 GHz planar circuit balanced Nb--Nb superconductor-insulator-superconductor (SIS) quasiparticle…
Terahertz hot electron bolometer waveguide mixers for GREAT
P. Pütz, C. E. Honingh, K. Jacobs +3
Supplementing the publications based on the first-light observations with the German Receiver for Astronomy at Terahertz frequencies (GREAT) on SOFIA, we present background informa…
Balanced superconductor-insulator-superconductor mixer on a 9~m silicon membrane
M. P. Westig, K. Jacobs, J. Stutzki +3
We present a 380-520 GHz balanced superconductor-insulator-superconductor (SIS) mixer on a single silicon substrate. All radio-frequency (RF) circuit components are fabricated on a…
