Abstract
At room temperature, YBCO possesses a relatively high temperature coefficie
nt of resistance, -3.5% K-1, and a high pyroelectric coefficient, up to 20
mu C cm(-2) K-1. In this work, we report on the cryogenic characterization
of semiconducting Y-Ba-Cu-O thin films on substrates in response to 100 fs
optical pulses at 810 nm and suspended thin film pixels in response to chop
ped broadband infrared radiation. The temperature dependence of the zero-bi
as pyroelectric response of the detectors is reported.
