Abstract

Sn{sub 1-x}/Si{sub x} cluster assembled films have been prepared by an energetic cluster impact deposition using a plasma-gas-condensation cluster beam deposition apparatus. Transmission electron microscope images indicated that individual clusters have composite morphologies, where Sn and Si were separated from each other. The superconducting critical magnetic fields, H{sub c}, of Sn{sub 1-x}/Si{sub x} cluster assembled films were measured and found to be much higher than the critical magnetic field of the bulk Sn. We estimated the H{sub c} values by using a theory of the superconducting thin film. The estimated values are in good agreement with the experiments, indicating that the Sn{sub 1-x}/Si{sub x} cluster assembled films can be regarded as a two-dimensional system although thickness, t, of Sn{sub 1-x}/Si{sub x} cluster assembled films (t Almost-Equal-To 1000 nm) is thicker than conventional superconducting thin film (t < 100 nm).

Superconductivity in Nb-Sn Thin Films of Stoichiometric and Off-Stoichiometric Compositions

Journal Article Mentink, M. G. T. ; Bonevich, John E. ; Dhalle, M. M. J. ; ... - IEEE Transactions on Applied Superconductivity

Binary Nb-Sn thin film samples were fabricated and characterized in terms of their composition, morphology, and superconducting properties. Nb-Sn was magnetron-sputtered onto heated R-plane sapphire substrates at 700 °C, 800 °C, and 900 °C, using a custom-built heater assembly. Samples were cut into strips, where each strip has a unique composition. For a subset of the samples, Nb-Sn was selectively etched away at an etching rate of 6 ± 1 nm/s using an aqueous solution of 3 vol. % hydrofluoric and 19 vol. % nitric acid. The sample composition was investigated with a scanning electron microscope with an X-ray energymore »« less

Critical Currents of Ex-Situ YBa ₂Cu ₃O _7-δ Thin Films on Rolling Assisted Biaxially Textured Substrates: Thickness, Field, and Temperature Dependencies

Journal Article Ijaduola, Anota O ; Thompson, James R ; Feenstra, Roeland ; ... - Physical Review B

The critical current density J{sub c} flowing in thin YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) films of various thicknesses d has been studied magnetometrically, both as a function of applied field H and temperature T, with a central objective to determine the dominant source of vortex pinning in these materials. The films, grown by a BaF{sub 2} ex situ process and deposited on buffered rolling assisted biaxially textured substrates ('RABiTS') substrates of Ni-5% W, have thicknesses d ranging from 28 nm to 1.5 {micro}m. Isothermal magnetization loops M(H;T) and remanent magnetization M{sub rem}(T) in H=0 were measured with H{parallel}c-axis (i.e., normalmore »« less

Study of fabrication problems with Nb/sub 3/Sn films used for Josephson tunnel junctions

Thesis/Dissertation Houck, L L

The fabrication of superconductive Nb/sub 3/Sn thin films was done by two different techniques, composite target sputtering and the reaction of elemental films. Both techniques deposited films onto cooled substrates and then used annealing to form the high T/sub c/, A15 phase of the films. Transition temperature of 17.9 to 18.0K measured resistively were routinely achieved. Composite target films needed a surface-modification procedure before tunnel junctions showing large energy gap could be made. A range of fabrication parameters were tried. Reaction method films were mace by varying the Nb/Sn ratio, annealing temperature, sputter etch depth in sputter cleaning and cathodemore »« less
Ge{sub 1−x−y}Si{sub x}Sn{sub y} light emitting diodes on silicon for mid-infrared photonic applications

Journal Article Gallagher, J. D. ; Xu, C. ; Menéndez, J. ; ... - Journal of Applied Physics

This paper reports initial the demonstration of prototype Ge{sub 1−x−y}Si{sub x}Sn{sub y} light emitting diodes with distinct direct and indirect edges and high quality I-V characteristics. The devices are fabricated on Si (100) wafers in heterostructure pin geometry [n-Ge/i-Ge{sub 1−x−y}Si{sub x}Sn{sub y}/p-Ge(Sn/Si)] using ultra low-temperature (T < 300 °C) depositions of the highly reactive chemical sources Si{sub 4}H{sub 10}, Ge{sub 4}H{sub 10}, Ge{sub 3}H{sub 8}, and SnD{sub 4}. The Sn content in the i-Ge{sub 1−x−y}Si{sub x}Sn{sub y} layer was varied from ∼3.5% to 11%, while the Si content was kept constant near 3%. The Si/Sn amounts in the p-layer were selected to mitigatemore »« less

Effect of Yb Substitution on Microstructure and Superconducting Properties of Y{sub 1−x}Yb{sub x}Ba{sub 2}Cu{sub 3}O{sub 7−δ} Films

Journal Article Li, Chunyan ; Suo, Hongli ; Ye, Shuai ; ... - Journal of Superconductivity and Novel Magnetism

The purpose of this study was to improve the critical current density (J{sub c}) of YBa{sub 2}Cu{sub 3}O{sub 7−δ} (YBCO) superconducting films at high magnetic fields. Thin Y{sub 1−x}Yb{sub x}Ba{sub 2}Cu{sub 3}O{sub 7−δ} (Y{sub 1−x}Yb{sub x}BCO) superconducting films on LaAlO{sub 3} substrates were prepared by modified low-fluorine metal organic deposition method (LF-MOD) in order to investigate the effect of Yb substitution on the microstructure and superconducting properties of a YBCO-coated conductor. In this study, single-phased, c-axial-aligned Y{sub 1−x}Yb{sub x}BCO films were obtained. Yb doping had a little effect on the critical temperature (T{sub c}) and transition width (ΔT) values ofmore »« less
