Abstract
We describe SIN (superconductor-insulator-normal) tunnel junctions mad e by thin-films of Nb/AlOx/Cu and we report on the measurements of the ir I-V characteristics between 10 K and 0.3 K. The junctions show a st rong dependence of the subgap conductance on the temperature, which ma kes them suitable for the on-chip measurement of the temperature. In t his paper we also describe the design of an on-chip electronic refrige rator based on this type of junctions.
