Preparation of Thin and Thick Film Superconductors in the Tl-Ca-Ba-Cu-O Systemed and limited chemical stability. Further, the T. of these materials near 90K is probably too close to 77K for many applications. These limitations mean substantial hurdles to the practical utilization of the (Re)Ba.Cu.O. materials.

Laser Ablation Analysis of 1-2-3 Material Control of the laser pulse and appropriate analysis of the vapor produced are necessary to understand the species that deposit on the substrate. Models for the laser-target interaction, the target plasma formation, and propagation to the substrate using a modified hydrodynamics code are presented.

As-Deposited Superconducting Y-Ba-Cu-O Thin Films on Si, SiO2, GaAs and Ni/Cu Substrates by High Preby solid state reaction. The substrate temperature is lower than 450°C. X-ray analysis indicates that the 0.6~2μm films consist of predomintly the orthorhombic superconducting phase of YBa.Cu.O. with traces of CuO. The effect of processing parameters on the superconductivity of the films will be discussed.

The Effect of Annealing Conditions on Laser Deposited Superconducting Bi-Sr-Ca-Cu-O Thin Filmsmeters produces films of optimal quality. The optimum processing parameters for a given film/substrate structure is of obvious interest. The range of these parameters which can produce films of near optimum quality is also important since this indicates how critical the processing is.

Preparation of High Temperature Superconductor Thin Films on Si Based Substrates by Excimer Laser Abn be DC biased. With the various biasing/plasma conditions we have studied to date, we have been unable to lower the substrate deposition temperature required for crystallization of Y-Ba-Cu-O films by more than 50 degrees C. Films of Y-Ba-Cu-O produced upon Si (111) are shown to be superconducting.

Properties of Y-Ba-Cu-O Thin Films Grown in-Situ at Low Temperatures by Co-Evaporation and Plasma Oxilms that have never been exposed to atmosphere. The films are also characterized by resistivity, critical currents, x-ray diffraction, energy and wavelength dispersive spectroscopy (EDS and WDS), inductively coupled plasma spectroscopy (ICP), SEM and TEM.
