Abstract

We have developed YBa2Cu3O7-x (YBCO) thermometers for large-area (4 mm x 4 mm) electrical substitution bolometers. We passivated the YBCO with a thin Au layer and demonstrated a noise equivalent temperature of 4 nK Hz-1/2. We then used a resistor layer of NiCr alloy deposited directly on the thermometer to perform optical measurements of the bolometer in the cryostat. Optical measurements show an electrical noise equivalent power of 87 pW Hz-1/2 with a large thermal conductance of 1.87 x 10-3 W K-1. these thermometers may be used as a real-time measurement radiometer.
