摘要：

The first fabrication of large area, 3 inch diameter, thin films of thallium based superconductors are reported. (Tl0.5Pb0.5)Sr2Ca2Cu3O9 thin films on LaAlO3 are found to display the best surface resistance, R-S, properties of any superconductor at higher temperatures and show approximately 50x better performance than copper at 100 K and 10 GHz. A Tl2Ba2CaCu2O8 thin film, processed as a 1.8 meter long, 10 micron wide meander line carries about 1x10(7) am ps/cm(2) at 4.2 K and 2x10(6) amps/cm(2) at 80 K. The thallium based superconductors are compared to YBa2Cu3O7 in Tc, Rs, and Q.
