Preface

Let us remember: One book, one pen, one child, and one teacher can change the world.

The word ceramic may be most misunderstood scientific concept so far as its public image is concerned. Most people, when they hear the word ceramic, are likely to think of such things as coffee mugs, glazed pottery, floor tile, or bathroom toilets. It is largely unknown to the public, or even to many scientific communities, that the use of ceramic materials goes far beyond these products.

Ceramic materials by definition are based on inorganic raw materials. Oxides form the leading group of electroceramic materials. Aluminum oxide (Al2O3), silicon carbide (SiC), silicon nitride (Si3N4), titanium oxide (TiO2), iron oxides (FeO, Fe2O3, Fe3O4), zinc oxide (ZnO) and tin oxide (SnO2) are typical examples. As for non‐traditional applications ceramics are used in aerospace and other extreme temperature applications due to their excellent thermal properties; in the medical field, ceramics are used because of their compatible with the human bone; and, in the military ceramics are used for applications such as body armor due to their extreme hardness.

The subject of this book is Electroceramic which is a special category of electronic materials. Electroceramic materials, as the name suggests, conduct electric currents obeying various physical mechanisms of current transport. These materials can exhibit a host of physical properties including high temperature superconductivity, magnetism, semiconductor, electro-optic, acousto-optic and nonlinear dielectrics. Because of their multi-faceted physical and mechanical properties these materials are poised to impact the advancement of ultrafast computer memory technology, green energy technology, sensors and detector technology as well as many other emerging areas of applied sciences and engineering. The field of electroceramic devices and applications is vast and diverse. It already impacts many areas of engineering and basic sciences such as microelectronics, solid‐state sciences, microwave engineering, communication engineering, signal processing, actuators and sensors and micro‐electro mechanical systems (MEMS) technology.

Electroceramic materials possess many interesting physical phenomena and that is what makes them fascinating and attractive for scientific discoveries leading to novel innovations. The physical principles involved in the origin of electroceramic phenomena are intriguing and so diverse that its intellectual challenges can be felt in a wide range of engineering and basic science disciplines. Yet electroceramic is not the household word even among electrical engineers, materials scientists, and applied physicists. Hardly anywhere a course devoted to electroceramics is offered in the US universities for electrical engineers, materials scientists, and physicists. As a result students are deprived of the knowledge in topics specific to electroceramic and its applications. Some examples may include noncentrosymmetric crystals, symmetry elements, piezoelectricity, ferroelectricity, pyroelectricity, multiferroic materials and phenomena, magnetoelectronics, spintronics, coupled hybrid devices, colossal magnetoresistive effect, giant photovoltaic effect, and energy harvesting.

The ignorance about electroceramics is pervasive. For example, many of the electrical engineering graduates and practitioners have never heard of varistor devices though almost all electrical engineering curriculums include a course or two on solid‐state materials and devices. It is disappointing and yet amusing. Bipolar varistors diodes are very useful devices that are present in practically all electrical and electronic circuits as circuit protectors against abrupt surges of current or voltage. Not only that varistors are forerunners of transistors, which are named so because of certain attributes they share with varistors.

Those of us working in the area of electroceramic materials and devices believe that it deserves its own separate presence in the curriculum of electrical engineering, materials science and applied physics; as well as of ceramic engineering, and perhaps also of mechanical and chemical engineering. The nature of elecroceramics is interdisciplinary and therefore, such a course could be cross listed to be taught in many technical disciplines.

The motivation to write this book came to me in the Fall of 2010 when for the first time I offered a special topic course on electroceramics for electrical engineering and physics students at Texas State University, San Marcos, TX. After teaching for 30 plus years, courses on electronic materials and solid‐state sciences at graduate and undergraduate levels at Texas A&M University and at the University of Alabama, I was confident that I would have no problems in handling this course. I had more than enough of my own lecture notes and homework problems on topics related to electroceramics. But finding a good textbook to recommend to students became a formidable enterprise. There are many books on electroceramics, but just one or two that could qualify for a text book. But they are simply too old by now and therefore inadequate for a text book. Many of the new advancements and discoveries made during the last 10–15 years are conspicuously absent in these books. As a result my resolve became stronger to undertake the task of writing a text book on electroceramics. I discussed this informally with many of my friends and colleagues at different universities, and all of us agreed that we need a new text book on the subject. Mr. Mark Mecklenborg and Mr. Greg Geiger of the American Ceramic Society also encouraged me to write such a book.

The book is divided in 11 chapters beginning with the essential elements of solid‐state science and ending in electro‐optics and acousto‐optics. I have done my best to develop each chapter in such a way that a good student can follow the materials easily and enjoy learning about them. Separate chapters are devoted to materials processing, characterization, and crystallography including noncentrosymmetric crystals and symmetry elements. Coupled dielectric phenomena such as piezoelectricity, ferroelectricity, and pyroelectricity have been covered in two chapters; a separate chapter is devoted to electroceramic semiconductors, and so are individual chapters on green energy, magnetism, electro‐optics and acousto‐optics. Each chapter includes some practical examples that should be helpful in understanding the theoretical concepts discussed. I have purposely tried to keep the use of advanced mathematics just adequate enough to make the theoretical concepts understandable without intimidating the students.

Each chapter also includes suggestions for advanced reading for the benefit of interested readers. At the end of each chapter, a glossary of technical terms has been added. Students are advised to look at them first before beginning to read the materials covered in the chapter. Also a set of homework problems have been added to each Chapter. I encourage students to work out all of them thoroughly and completely because it will solidify and amplify their insight into the subject matter and give them confidence and pleasure of learning.

I owe gratitude to a long list of individuals and institutions. First and foremost, I must thank my dear wife, Dr. Christa Pandey, who has been an inspiring influence throughout my long journey in life and supportive of all my professional endeavors. Her unwavering confidence in my abilities to excel professionally has been my strength and has given me the confidence to undertake the challenges that comes naturally in executing a project such as writing a text book.

I also must thank all my former students at Texas A&M University at College Station, and at the University of Alabama at Tuscaloosa, AL, whom I had the honor of teaching one or more courses during the span of 30 years. That experience and the challenges I had to face made me a better class room teacher and a good researcher. But the driving force behind this book were my students at Texas State University at San Marcos, TX, whom I had the pleasure of teaching a special topic course on electroceramics three times. Their enthusiasm and dedication to learning and doing research in labs even as undergraduate seniors were contagious. To all these students, I owe gratitude and give my very sincere thanks for the doors they opened. Thanks also to two of my former graduate students, Dr. Jian Zhong and Dr. Hui Han, who critically reviewed one chapter each and pointed out to some of the lapses which I subsequently corrected.

My gratitude and thanks also to my friends and colleagues, Professor Rick Wilkins of Prairie View A&M University and Professors Ravi Droopad, Harold Stern and William A. Stapleton of Ingram School of Engineering at Texas State University. They were gracious and patient enough to go over two or more chapters and provide me with their suggestions and comments. All of them were valuable suggestions and I have revised these chapters incorporating all of their suggestions,

My thanks go also to my gifted grand‐daughter, Dr. Alysha Kishan, for proposing multiple designs for the cover page and for teaching me the fine points of making good graphics. This has added to the looks and quality of the book. I am thankful to all the publishers who have been gracious enough to grant us permission for reproducing their copyrighted materials. I also owe thanks to institutions such as Sterling C. Evans Library at Texas A&M University and Rodgers Library for Science and Engineering of the University of Alabama for the privilege of...
