Book excerpt: Two methods for identify point defects applicable to the study of technologically relevant pyroelectric oxide materials have been investigated, namely Positron Annihilation Lifetime Spectroscopy (PALS) and Electron Paramagnetic Resonance (EPR). For this study a PALS spectrometer was constructed. Preliminary PALS and EPR results on powder and ceramic materials are presented. An operational positron annihilation lifetime spectrometer has been constructed and tested. The resolution function width of approximately 205 ps with a count rate of 130 counts S( -1) from a 370 kBq( -1) source was achieved. Two independent analysis algorithms were tested using simulated lifetime spectra. Systematic studies were performed on a series of polycrystalline pure metal samples. This work confirmed the need for accurate source annihilation correction and allowed a methodology to be developed. Further, this procedure allowed the variation in backscatter source contribution with atomic number to be studied. The spectrometer was then used to study two pyroelectric Pb based perovskite oxide ceramic samples, a La doped PZT sample, (Pb, La)(Zr, Ti)O3, and an undoped Pb(Sc(0.5), Ta(0.5))O3 (PST) sample. Fits using maximum entropy method and source corrected fitting using non-linear least square where found to be similar. A second vacancy defect contribution was clearly observed in both samples. Electron paramagnetic resonance measurements were extended from earlier single crystal PbTiO3 work to powder Pb(Zr, Ti)O3 samples. A series of Mn doped samples was studied. The spectrum was found to contain contributions from both Mn(4+) and Mn(2+) charge states.

Download or read book Characterisation of Ferroelectric Bulk Materials and Thin Films written by Markys G. Cain and published by Springer. This book was released on 2014-06-02 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive review of the most important methods used in the characterisation of piezoelectric, ferroelectric and pyroelectric materials. It covers techniques for the analysis of bulk materials and thick and thin film materials and devices. There is a growing demand by industry to adapt and integrate piezoelectric materials into ever smaller devices and structures. Such applications development requires the joint development of reliable, robust, accurate and – most importantly – relevant and applicable measurement and characterisation methods and models. In the past few years there has been a rapid development of new techniques to model and measure the variety of properties that are deemed important for applications development engineers and scientists. The book has been written by the leaders in the field and many chapters represent established measurement best practice, with a strong emphasis on application of the methods via worked examples and detailed experimental procedural descriptions. Each chapter contains numerous diagrams, images, and measurement data, all of which are fully referenced and indexed. The book is intended to occupy space in the research or technical lab, and will be a valuable and practical resource for students, materials scientists, engineers, and lab technicians.
