Abstract
Photoresponse of BiPbSrCaCuO superconductor films was studied at normal state temperatures. At room temperature, responsivity in the range of 10 – 100 V/MW was seen to remain constant over at least 8 orders of magnitude of incident power. Detectors were manufactured on films with a thickness as small as 20 nm, showing a time constant shorter than 10 ns. Investigation of photoresponse characteristics showed consistency with a tensorial Seebeck effect in off c-axis grown films. These characteristics suggest that uncooled BiPbSrCaCuO films may be useful replacements for pyroelectric power meters and photon drag detectors.
