We report the growth of c-axis oriented, epitaxial thin films of (Tl,Pb)Sr/sub 2/CuO/sub 5/ on (100) oriented LaAlO/sub 3/ substrates by off-axis sputter deposition in the presence of thallium oxide vapor. These films display a resistivity which cros

The nonlinearity or microwave surface resistance of high temperature superconductors (HTS) is of considerable interest. We report the first measurement of the 3rd order intercept (TOI) from harmonic generation for HTS. The nonlinearities were measure

The use of high temperature superconducting thin films in chip-to-chip interconnects requires the fabrication of long, narrow lines capable of carrying high current density on large area films. The capability of Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub 8/

Epitaxial TlBa/sub 2/CaCu/sub 2/O/sub 7/ thin films have been grown on single-crystal LaAlO/sub 3/, NdGaO/sub 3/, and CeO/sub 2/ buffered sapphire substrates by in situ off-axis magnetron sputtering in the presence of Tl/sub 2/O vapor. Phase formatio

The first fabrication of 3-in-diameter, thin films of thallium-based superconductors is reported. (Tl/sub 0.5/Pb/sub 0.5/)Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub 9/ thin films on LaAlO/sub 3/ are found to display the best surface resistance (R/sub s/) prope

An AC inductance technique combined with a variable DC magnetic field has been used to measure at 77 K the flux exclusion properties of thin films of the high-temperature superconductors YBa 2 Cu 3 O 7− x and Tl 2 Ba 2 CaCu 2 O 8 , prepared by coev

High-quality films were produced by coevaporation and cosputtering of Y, Cu, and BaF/sub 2/ followed by an ex-situ anneal. The Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7-x/ films produced had microwave surface resistances as low as 1/10 that of Cu at 77 K and

We present the first femtosecond pump-prove measurements of the room temperature optical properties of high-Tc superconductors. Three oriented superconducting thin-films were studied: YBa2Cu3O7−δ, Bi2Sr2CaCu2O8+z, and Bi2Sr2Ca2Cu3O10+y. The observ

We report the growth of thin films of (Tl,Pb)Sr2Ca1−xYxCu2O7 with x=0–0.2 by off‐axis magnetron sputtering in the presence of thallium oxide vapor. The (Tl,Pb)Sr2Ca1−xYxCu2O7 films are highly c‐axis oriented on the pseudocubic (100) surface
