Abstract: Abstract of thesis entitled FABRICATION AND CHARACTERIZATION OF EPITAXIAL YBa Cu O 2 3 y THIN FILMS ON DOUBLE-BUFFERED SILICON SUBSTRATES submitted by WONG HO YI ERIC for the degree of Master of Philosophy at The University of Hong Kong in August 2003 The discovery of perovskite copper oxide YBa Cu O (YBCO) has aroused a 2 3 y constantly increasing interest in this material due to the potential applications in microelectronics devices, such as microwave elements, multilayer junctions, etc. Suitable substrates with a low dielectric constant, good high frequency properties, large size and low cost are necessary. Silicon substrates are widely used and well developed in the semiconductor industry and microwave device applications. Therefore, successful fabrication of high T YBCO films on silicon is of interest for various applications of hybrid superconductor-semiconductor devices and interconnected circuits. In such applications, the epitaxial growth of YBCO on silicon is extremely important. This thesis presents a systematic investigation of the fabrication and characterization of epitaxial YBCO thin films on silicon substrates with a double buffer of Eu CuO (ECO)/YSZ(Yttria-Stabilized Zirconia). Silicon (001) substrates 2 4 were prepared using a chemical etch by dilute HF acid prior to thin film deposition. The YBCO thin films were grown via an entirely in situ process using an on-axis rf magnetron sputtering method with optimized deposition parameters including the deposition temperature, operating pressure and partial oxygen pressure. The crystallinity, surface morphology, electrical properties, and interface of the obtained YBCO/ECO/YSZ thin films were studied by x-ray diffraction, surface profiler, atomic force microscope, optical microscope, standard dc four-probe measurements and small angle x-ray reflection. The X-ray diffraction patterns showed that all the thin films were highly c-axis oriented. A full width of 0.69 at half maximum of the YBCO(005) peak was obtained. This was smaller than reported in previous studies of YBCO thin films on double buffered silicon or nickel substrates. The atomic force microscopy image showed that the ECO buffer surface was flat and smooth. The average roughness over a wide scanning region of 2000m was less than 25nm. The optical microscope images showed that the surface morphology of the grown YBCO thin films was significantly improved by the ECO buffer layer since ECO had a very stable 214-T' crystal structure and very small lattice mismatch with YBCO. The YBCO/ECO/YSZ multilayers were further characterized by small angle x-ray reflection. The surface roughness of the YBCO layers decreased when an ECO buffer was added. No intermediate layer was found at the YBCO/ECO and ECO/YSZ interfaces. The results suggest that ECO is chemically compatible with YBCO and YSZ. The superconductivity of YBCO films was significantly improved by the ECO/YSZ double buffer. This is indicated by the fact that YBCO thin films on silicon substrates with an ECO/YSZ double buffer showed a higher T than that grown on YSZ/Si without the ECO layer. The advantages of using ECO/YSZ double buffer layers in deposition of YBCO on silicon were clearly demonstrated. It would provide a good basis for the potential applications of YBCO on other semiconductors, metallic or me
Book Synopsis Second-Generation HTS Conductors by : Amit Goyal
Download or read book Second-Generation HTS Conductors written by Amit Goyal and published by Springer Science & Business Media. This book was released on 2006-06-26 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third method invented is called the Rolling-assisted-biaxially-textured-substrates (RABiTS). The book is divided into four sections. The first section discusses the three methods to fabricate biaxially textured substrates, upon which, epitaxial YBCO or other HTS materials can be deposited to realize a single-crystal-like HTS wire. The second section includes chapters on various methods of HTS deposition such as pulsed laser ablation (PLD), thermal co-evaporation, sputtering, pulsed electron beam deposition, ex-situ BaF2 by co-evaporation flowed by annealing, chemical solution based ex-situ processes, jet vapor deposition, metal organic chemical vapor deposition (MOCVD), and liquid phase epitaxy (LPE). The third section includes detailed chapters on other HTS materials such as the various Tl-based and Hg-based conductors. These Second-Generation HTS conductors, also referred to as "Coated conductors" represent one of the most exciting developments in HTS technology.

Download or read book Vortex Electronics and SQUIDs written by Takeshi Kobayashi and published by Springer Science & Business Media. This book was released on 2003-12-08 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the nature of vortices in high-Tc superconductors is a crucial subject for research on superconductive electronics, especially for superconducting interference devices (SQUIDs), it is also a fundamental problem in condensed-matter physics. Recent technological progress in methods for both direct and indirect observation of vortices, e.g. scanning SQUID, terahertz imaging, and microwave excitation, has led to new insights into vortex physics, the dynamic behavior of vortices in junctions and related questions of noise. This book presents the current status of research activity and provides new information on the applications of SQUIDs, including magnetocardiography, immunoassays, and laser-SQUID microscopes, all of which are close to being commercially available.

Download or read book High Tc Superconductors written by J. Dumas and published by Elsevier. This book was released on 1993-05-05 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide range of progress in materials development [single crystals, ceramics, thin films, wire and tapes] is reported in the 169 papers in this volume. The main focus of the papers is in attaining a better understanding of the relationship between microstructure and electrical properties. Invited papers cover topics such as the effects of substitution and doping; multilayers; nanostructure characterisation; electric field effects in High Tc Superconductors [HTS]; surface stability; critical currents; flux pinning and magnetooptic imaging of flux patterns; effects of irradiation induced defects; properties and preparation of materials; microwave properties and electronic devices. A clearly broadened basis for understanding processes and mechanisms in [HTS] is portrayed. Appreciable progress has been achieved in the reproducible manufacturing of high quality materials supported by very efficient methods in microstructural analysis. This essential improvement is reflected in the increased number of practical devices encouraging the use of HTS in applications for electronics and power engineering, all of which are reviewed in depth in this work.

Book excerpt: By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.
