摘要

The spectral content of radiation incident on a bulk photoconductor can significantly affect the measured photocurrent. We show that front-illuminated Si:As bulk photoconductors operated at low temperature (approximately 10$DGR@K) are sensitive to the spectral characteristics of the background, as well as signal fluxes. Our analysis is applied to spectral response measurements on bulk photoconductors themselves, and to filter transmission measurements that have been made utilizing these devices as IR detectors.
