High critical currents in epitaxial YBa2Cu3O7−x thin films on silicon with buffer layers
X. D. Wu,A. Inam,M. S. Hegde,B. Wilkens,C. C. Chang,D. M. Hwang,L. Nazar,Thirumalai Venkatesan,Sadahiko Miura,Shogo Matsubara,Yoichi Miyasaka,Nobuaki Shohata +11 more
TL;DR: In this article, as-deposited superconducting thin films (∼0.1 μm) of YBa2Cu3O7−x have been prepared by pulsed laser deposition on (100) Si with buffer layers of BaTiO3/MgAl2O4.
Journal ArticleDOI
Substrate effects on the properties of Y‐Ba‐Cu‐O superconducting films prepared by laser deposition
T. Venkatesan,C. C. Chang,D. Dijkkamp,Satishchandra Ogale,E. W. Chase,L. A. Farrow,D. M. Hwang,P. F. Miceli,S. A. Schwarz,Jean-Marie Tarascon,X. D. Wu,A. Inam +11 more
TL;DR: In this paper, it was shown that the substrate lattice influences the film properties primarily in three ways: the thermal expansion mismatch introduces cracks in the film, the interface reaction changes the film composition, and the lattice lattice affects the crystallographic orientation of the film.
Journal ArticleDOI
Structural perfection of Y‐Ba‐Cu‐O thin films controlled by the growth mechanism
Ramamoorthy Ramesh,C. C. Chang,T. S. Ravi,D. M. Hwang,A. Inam,X. X. Xi,Qi Li,X. D. Wu,T. Venkatesan +8 more
TL;DR: In this article, the authors reported the observation of YBa2Cu3O7−x(123) thin films having unprecedented structural perfection, at temperatures near 700°C on [001] LaAlO3.
Journal ArticleDOI
Enhanced electronic properties of GaAs surfaces chemically passivated by selenium reactions
TL;DR: In this article, chemical modifications of GaAs surfaces are described, which produce robust selenium layers that significantly enhance the electronic properties of the surface and reveal significant AsSe bond formation at the surface.
Journal ArticleDOI
Large critical current densities in YBa2Cu3O7−x thin films made at high deposition rates
X. D. Wu,Ross E. Muenchausen,S. R. Foltyn,R. C. Estler,Robert C. Dye,A. R. Garcia,Nicholas S. Nogar,P. England,Ramamoorthy Ramesh,D. M. Hwang,T. S. Ravi,C. C. Chang,Thirumalai Venkatesan,X. X. Xi,Qi Li,A. Inam +15 more
TL;DR: In this article, critical current densities (Jc) in YBa2Cu3O7−x films made at deposition rates from 0.1 to 14.5 nm/s (∼50 μm/h) were measured using a direct transport method.
