Book excerpt: Thin film bulk acoustic wave (BAW) resonators and filters operating in the GHz range are used in mobile phones for the most demanding filtering applications and complement the surface acoustic wave (SAW) based filters. Their main advantages are small size and high performance at frequencies above 2 GHz. This work concentrates on the characterization, performance optimization, and modelling techniques of thin film BAW devices. Laser interferometric vibration measurements together with plate wave dispersion modeling are used to extract the full set of elastic material parameters for sputter deposited ZnO, demonstrating a method for obtaining material data needed for accurate simulation of the devices. The effectiveness of the acoustic interference reflector used to isolate the vibration from the substrate is studied by 1-D modeling, 2-D finite element method and by electrical and laser interferometric measurements. It is found that the Q-value of reflector-based BAW resonators operating at 2 GHz is limited to approximately 2000 by mechanisms other than leakage through the reflector. Suppression of spurious resonances in ZnO resonators is studied in depth by modeling and measurements. It is verified that the approximate mode orthogonality is behind the suppression in boundary frame type ZnO devices operating in the piston mode, but also another narrow band mode suppression mechanism is found. A plate wave dispersion based 2-D simulation scheme for laterally acoustically coupled BAW resonator filters is developed and employed in designing of experimental devices, which show both good agreement with the model predictions and a remarkable 4.9 % relative bandwidth.
Book Synopsis Microstructural Characterization of Materials by : David Brandon
Download or read book Microstructural Characterization of Materials written by David Brandon and published by John Wiley & Sons. This book was released on 2013-03-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructural characterization is usually achieved by allowing some form of probe to interact with a carefully prepared specimen. The most commonly used probes are visible light, X-ray radiation, a high-energy electron beam, or a sharp, flexible needle. These four types of probe form the basis for optical microscopy, X-ray diffraction, electron microscopy, and scanning probe microscopy. Microstructural Characterization of Materials, 2nd Edition is an introduction to the expertise involved in assessing the microstructure of engineering materials and to the experimental methods used for this purpose. Similar to the first edition, this 2nd edition explores the methodology of materials characterization under the three headings of crystal structure, microstructural morphology, and microanalysis. The principal methods of characterization, including diffraction analysis, optical microscopy, electron microscopy, and chemical microanalytical techniques are treated both qualitatively and quantitatively. An additional chapter has been added to the new edition to cover surface probe microscopy, and there are new sections on digital image recording and analysis, orientation imaging microscopy, focused ion-beam instruments, atom-probe microscopy, and 3-D image reconstruction. As well as being fully updated, this second edition also includes revised and expanded examples and exercises, with a solutions manual available at http://develop.wiley.co.uk/microstructural2e/ Microstructural Characterization of Materials, 2nd Edition will appeal to senior undergraduate and graduate students of material science, materials engineering, and materials chemistry, as well as to qualified engineers and more advanced researchers, who will find the book a useful and comprehensive general reference source.

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
