Huggard, P. G. and Zeuner, S. and Goller, K. and Lengfellner, Hans and Prettl, Wilhelm (1994) Normal state YBa2Cu3Ox films: A new fast thermal detector for far infrared laser radiation with a uniform wavelength response. Journal of Applied Physics 75 (1), pp. 616-618.
Room temperature YBa2Cu3Ox films, epitaxially grown on oriented substrates, are shown to be effective detectors of far infrared laser pulses. The photovoltage arises due to an anisotropic material thermopower subject to the thermal gradient arising from the radiation heating. For a 40 nm thick film we have measured a responsivity of (5±2)×10−7 V/W, independent of frequency in the range from 20 to ...
