Abstract
The possibility of using commercial RuO2 planar resistors as low-temperature radiation sensors was investigated. At temperatures of 0.08–0.1 K, their sensitivity to blackbody radiation at temperatures of 5–40 K was about 2–3 pW. The radiation absorption coefficient was <10%. The response is a linear function of the radiation power, thus indicating that the detector band is no narrower than 0.5–2.5 THz. The rise time of an output signal without feedback-assisted temperature stabilization was ~12 s owing to an unexpectedly high thermal capacity of the resistor.
