This comprehensive book is highly suitable for graduate school students and researchers who are not familiar with hybrid perovskite materials and devices, allowing the accumulation of the accurate knowledge from the basic to the advanced levels.




Characterization of Solid Materials and Heterogeneous Catalysts, 2 Volume Set


Book Description

This two-volume book provides an overview of physical techniques used to characterize the structure of solid materials, on the one hand, and to investigate the reactivity of their surface, on the other. Therefore this book is a must-have for anyone working in fields related to surface reactivity. Among the latter, and because of its most important industrial impact, catalysis has been used as the directing thread of the book. After the preface and a general introduction to physical techniques by M. Che and J.C. Vedrine, two overviews on physical techniques are presented by G. Ertl and Sir J.M. Thomas for investigating model catalysts and porous catalysts, respectively. The book is organized into four parts: Molecular/Local Spectroscopies, Macroscopic Techniques, Characterization of the Fluid Phase (Gas and/ or Liquid), and Advanced Characterization. Each chapter focuses upon the following important themes: overview of the technique, most important parameters to interpret the experimental data, practical details, applications of the technique, particularly during chemical processes, with its advantages and disadvantages, conclusions.







Cathodoluminescence and Photoluminescence


Book Description

Written by a senior industry expert with nearly 40 years of hands-on experience, Cathodoluminescence and Photoluminescence: Theories and Practical Applications presents a thorough review of advances, challenges, and recommendations for improving photoluminescent (PL) and cathodoluminescent (CL) phosphor display devices in terms of energy efficiency, image quality, color fidelity, operational lifetime, and production cost. This book traces the development of cathode ray tubes (CRTs), PL and CL phosphor screens, and fluorescent lamps (FL) into modern phosphor display devices. The author relates luminescence phenomena and color to chemical composition, excitation mechanisms, energy conversion efficiencies, and bulk properties of phosphor particles. He also addresses image quality issues such as flickering, smearing, whitening, and contrast. Subsequent chapters focus on powder deposition techniques and the production of phosphor powders themselves. The text describes the necessary raw materials, flux materials, and growth conditions for producing ZnS powders. It provides a quantitative analysis on optimal processes and parameters for ensuring higher quality color and screen resolution. Offering a detailed guide for next-generation scientists and engineers in the field, Cathodoluminescence and Photoluminescence describes current technologies and promising developments for producing higher quality, energy-efficient, and long-lasting phosphor CR and flat CL screen displays.




Optical Characterization of Semiconductors


Book Description

This is the first book to explain, illustrate, and compare the most widely used methods in optics: photoluminescence, infrared spectroscopy, and Raman scattering. Written with non-experts in mind, the book develops the background needed to understand the why and how of each technique, but does not require special knowledge of semiconductors or optics. Each method is illustrated with numerous case studies. Practical information drawn from the authors experience is given to help establish optical facilities, including commercial sources for equipment, and experimental details. For industrial scientists with specific problems in semiconducting materials; for academic scientists who wish to apply their spectroscopic methods to characterization problems; and for students in solid state physics, materials science and engineering, and semiconductor electronics and photonics, this book provides a unique overview, bringing together these valuable techniques in a coherent wayfor the first time.Discusses and compares infrared, Raman, and photoluminescence methodsEnables readers to choose the best method for a given problemIllustrates applications to help non-experts and industrial users, with answers to selected common problemsPresents fundamentals with examples from the semiconductor literature without excessive abstract discussionFeatures equipment lists and discussion of techniques to help establish characterization laboratories




Semiconductors


Book Description

The frequent use of well known critical data handbooks like Beilstein, Gmelin and Landolt Bornstein is impeded by the fact that merely larger libraries - often far away from the scientist's working place - can afford such precious collections. To satisfy an urgent need of many scientists for having at their working place a comprehensive, high quality, but cheap collection of at least the basic data oftheirfield of interest the series "Data in Science and Technology"is started now. This first volume presents the most important data on two groups of semiconductors, the elements of the IVth group of the periodic system and the III-V compounds. All data were compiled from information on about 2500 pages in various volumes of the New Series of Landolt-Bornstein. For each critically chosen data set and each figure the original literature is cited. In addition, tables of content refer to the handbooks the data were drawn from. Thus the presentation of data in this volume is of the same high quality standard as in the original evaluated data collections. We hope to meet the needs of the physical community with the volumes of the series "Data in Science and Technology", forming bridges between the laboratory and additional information sources in the libraries.




Experimental Methods


Book Description

Treatise on Materials Science and Technology, Volume 19: Experimental Methods, Part A covers the methods of materials experimentation and testing. The book discusses the measurement of residual stresses by x-ray diffraction techniques; the investigation of composition variations by diffraction; and the use of Mössbauer spectroscopy in materials science. The text also describes photoluminescence techniques for studies of composition and defects in semiconductors; and materials production by high-rate sputter deposition. Graduate students in the field of materials science, laboratory scientists, and materials engineers will find the book invaluable.




Environmentally Benign Photocatalysts


Book Description

Over the past few decades, mankind has observed an unprecedented and remarkable growth in industry, resulting in a more prosperous lifestyle for peoples of many countries. In developing countries, however, explosive industrial growth is just now beginning to raise the living standards of the people. Most industries, especially in these developing countries, are still powered by the burning of fossil fuels; con- quently, a lack of clean energy resources has caused environmental pollution on an unprecedented large and global scale. Toxic wastes have been relentlessly released into the air and water leading to serious and devastating environmental and health problems while endangering the planet and life itself with the effects of global warming. To address these urgent environmental issues, new catalytic and photocatalytic processes as well as open-atmospheric systems are presently being developed that can operate at room temperature while being totally clean and ef?cient and thus environmentally harmonious. Essential to technologies harnessing the abundant solar energy that reaches the earth are the highly functional photocatalytic proce- es that can utilize not only UV light, but also visible light.
