Abstract

Infrared detectors based upon high transition temperature ('high Tc') superconductors include superconducting transition edge microbolometers, nonequilibrium photoeffect detectors and photon-assisted tunneling detectors. Superconducting transition edge microbolometers offer moderate performance as individual detectors; a potential application is for large two-dimensional staring focal plane arrays. Experimental search for the nonequilibrium photoeffect in high Tc superconductors reveals unwanted bolometric signals. Photon-assisted tunneling in theory provides very high performance, but no experimental data are available.
