Normal metal–insulator–superconductor junction technology for bolometers

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 the required sub μ m 3 volumes and ohmic superconductor–normal metal contacts for delivering power...

Description
Summary: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 the required sub μ 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.
