Highly c-axis-oriented Tl2Ba2CaCu2O(x) thin films were grown on MgO(100) by MOCVD and post annealing processes. Resistive transitions of 105 K, critical current densities as high as 100,000 Amps/sq cm (4 K) and surface resistivities 1/2 to 1/5 that of a gold standard at 17 GHz (77 K) were obtained with unpatterned films. Thin TlBaCaCuO films functioned as bolometric detectors over a spectral range of 1.5 to 20 micron; no quantum or nonequilibrium effects were observed between 4 and 125 K. Fine features were delineated in the BaCaCuO thin films by wet chemical etching. After Tl incorporation, resistive transitions exceeding 103 K were observed in the patterned films.
