Abstract

Normal metal-insulator-superconductor tunnel junctions are candidates for large-format arrays of ultra-low noise equivalent power bolometers. Using a wafer scale process we have fabricated devices with required the sub $\mu}$m$^3}$ volumes and ohmic superconductor-normal metal contacts for delivering power loads. Additionally, we demonstrate simultaneous tunnel junction thermometry and SQUID based Johnson current noise thermometry.
