摘要:
Applicants have discovered that films of conductively doped GaInO.sub.3 grown on substrates by pulsed laser deposition have conductivity comparable to conventional wide band-gap transparent conductors while exhibiting superior light transmission, particularly in the green and blue wavelength regions of the visible spectrum. Substrate temperatures ranged from room temperature to 350.degree. C. in an ambient containing oxygen at partial pressure in the range 0.1 mTorr to 100 mTorr. The preferred laser source was an excimer laser operating in the deep ultraviolet.

Applicants have discovered that films of conductively doped GaInO.sub.3 grown on substrates by sputter deposition have conductivity comparable to conventional wide band-gap transparent conductors while exhibiting superior light transmission, particularly in the green and blue wavelength regions of the visible spectrum. Substrate temperatures ranged from 100.degree. C. to 550.degree. C. in an argon-oxygen ambient of total pressure 4 mTorr to 20 mTorr with an optimal oxygen partial pressure in the range 0.5 to 2 mTorr.
摘要:
A novel intermetallic superconductor with surprisingly high transition temperature is disclosed. Exemplary of the novel superconductor is material of overall composition Y.sub.1.5 Pd.sub.4.5 B.sub.4. A bulk sample of that composition has T.sub.c (onset) of 22.6K, with about 0.5 volume % of the sample being superconducting.

Novel superconductive Pb-substituted oxides are disclosed. The oxides all have layered perovskite-like crystal structure, and manifest superconductivity (R=o) above about 77K. The materials are described by the nominal formula X.sub.2+x M.sub.3-x Cu.sub.2 O.sub.8.+-..delta., where X is Bi and Pb, M is Sr and Ca, 0.ltoreq..times..ltoreq.0.3, 0.ltoreq..delta..ltoreq.0.5, the Pb/Bi ratio is between about 0.2 and about 0.5, and the Sr/Ca ratio is between 0.5 and 2.
