ABSTRACT:
A thermoelectric radiation detector having a substrate (1) and a film (2) of solid state material having thermal anisotropy and containing YBa.sub.2 Cu.sub.3 O.sub.7, formed on the surface of the substrate, and wherein said film has CuO.sub.2 planes (3) inclined with respect to the substrate plane, the improvement wherein at least a portion of the Y is replaced by another rare earth metal and/or at least a portion of the Ba and/or of the Cu is replaced by at least one other heavy metal at least in partial areas of the film and in a sufficient amount to increase the thermal anisotropy of the detector.
