Low-Temperature Radiation Detectors Based on Ruthenium-Oxide Resistors


Bolometers based on industrial planar resistors were manufactured and studied. In the frequency range of 200–400 GHz, they showed a sensitivity of 6 × 10–12 Ω/W (which corresponds to a power of absorbed radiation of ~10 pW at a measuring current of about 1 nA) in the dynamic range of ~30 dB at an operating temperature of 0.3 K. By comparing the detector response to incident radiation with the response to a change in its resistance with increasing the direct current power, it is possible to determine the absolute power of absorbed radiation with an accuracy of 10–20%. The time constant of the used ruthenium-oxide detectors, depending on the substrate thickness, is ~0.1–2 s.
