Abstract
We have fabricated and characterized six-element monolithic arrays of Ge:Ga blocked- impurity-band detectors, with threshold wavelength 220 μm, peak quantum efficiency 14%, detective quantum efficiency 9%, dark current 300 e− s−1, and response uniformity better than 4%. The devices are described very well by the standard model of blocked-impurity-band detectors, and appear to satisfy many of the requirements of low-background astronomical instruments.
