We have prepared superconducting thin films of (Y,Yb)Ba sub 2 Cu sub 3 O sub (7-delta) by evaporation of copper, ytterbium or yttrium, and barium fluoride from Knudsen effusion cells.
High T sub c and J sub c superconducting films of Ba sub 2 YCu sub 3 O sub 7 are prepared on (100) SrTiO sub 3 substrates using pulsed excimer laser vaporization of a composite target containing B

A technique is described for preparing superconducting cuprate thin films using wet chemical precursors.
Superconducting films of Ca-Sr-Bi-Cu oxides have been prepared by coevaporation of CaF sub 2, SrF sub 2, Bi and Cu, followed by post oxidation in wet O sub 2.
Phosphor materials are important in cathode ray tube (CRT) and electroluminescent display technologies, and development in these materials may lead to competitive edges in many AT&T products wi
The discovery of high temperature superconductors offers a potential for significant technological applications, and has caused unprecedented excitement and explosion of research and development.
