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.This publication has 12 references indexed in Scilit:
