Abstract

We report on the strong bolometric response of doped stannic oxide single crystals to submillimeter radiation. As confirmed up to 120 kG, the magnetic field dependence of the bolometric response is negligible. The bolometer responsivity at zero frequency has been evaluated from the load curve and compared with the corresponding data of the Ge bolometer. The new detector has been used successfully in a magnetic field to detect the electron cyclotron resonance in InSb.
