摘要：

We discuss the characteristics of impurity band conduction detectors prepared from epitaxial Si:Sb. These detectors are sensitive to infrared light at wavelengths between 2.5 and 40-mu-m and outperform the current state-of-the-art Ge:Be photoconductors for this wavelength range by a combination of a peak responsivity R = 32 A/W, low noise equivalent power (NEP) = 1.1 X 10(-15) W/Hz1/2 (at a flux of 10(12) ph/cm2 s), inherently low sensitivity to cosmic ray particles, and freedom from the anomalous behavior observed in photoconductors.
