dc.description.abstract | We report the development of superconducting tantalum nitride (TaN
x
) normal
metal-insulator-superconductor (NIS) tunnel junctions. For the insulating barrier, we used both
AlO
x
and TaO
x
(Cu-AlO
x
-Al-TaN
x
and Cu-TaO
x
-TaN
x
), with both devices exhibiting temperature
dependent current-voltage characteristics which follow the simple one-particle tunneling model.
The superconducting gap follows a BCS type temperature dependence, rendering these devices
suitable for sensitive thermometry and bolometry from the superconducting transition temperature
T
C
of the TaN
x
film at
5 K down to
0.5 K. Numerical simulations were also performed to
predict how junction parameters should be tuned to achieve electronic cooling at temperatures
above 1 K.
