The capability and performance of compensated Si (Sb ∼ 2×1018 cm−3; B ∼ 2×1017 cm−3) impurity conduction bolometers as extremely sensitive detectors of far-infrared radiation (2 mm to 30 μm) is described. Electrical and far-infrared measurements indicate a NEP ∼ 2.5×10−14 W/Hz1/2, and a response time ∼ 10−2 sec, when operated at 1.5°K.
