Both DyBaCuO (DBCO) and YBaCuO (YBCO) films deposited on a variety of substrates have been investigated for their applicability as detectors of high frequency radiation. Both 10 GHz and infrared radiation (IR) were used as the high frequency radiation source. The measurements consisted of monitoring the temperature dependent resistance of superconducting films both in the presence and absence of radiation. This investigation shows that because the superconducting transition temperature is sensitive to the magnitude of the current in the film, the temperature dependence of the bolometric response is slightly tunable. In addition, effects of radiation on the current voltage characteristics below T superconducting were studied. This study found that films in this regime could also serve as radiation detectors. The substrates used included MgO, SiO, LaAlO(subscript 3), and SrTiO(subscript 3). The results obtained were independent of the substrate except for the width of the resistive transition. Disorder in the films as characterized by the resistive transition, affected the microwave more than the IR response.
