Scientific paper

The characteristics of blocked impurity-band (BIB) conduction detectors prepared from epitaxial Si:Sb, detectors which are suitable for IR spectroscopy of redshifted galaxies, the ISM, and star formation are discussed. The first of these detectors perform better than state of the art Ge:Be photoconductors (PCs) in the 30-40 micron range and are responsive to wavelengths down to 2.5 microns. They are also inherently insensitive to cosmic rays and free from the anomalous effects observed in PCs.
