Tremendous progress has been made in the last few years in the growth, doping and processing technologies of the wide bandgap semiconductors. As a result, this class of materials now holds significant promis for semiconductor electronics in a broad range of applications. The principal driver for the current revival of interest in III-V Nitrides is their potential use in high power, high temperature, high frequency and optical devices resistant to radiation damage. This book provides a wide number of optoelectronic applications of III-V nitrides and covers the entire process from growth to devices and applications making it essential reading for those working in the semiconductors or microelectronics. Broad review of optoelectronic applications of III-V nitrides

Organized nanoassemblies of inorganic nanoparticles and organic molecules are building blocks of nanodevices, whether they are designed to perform molecular level computing, sense the environment or improve the catalytic properties of a material. The key to creation of these hybrid nanostructures lies in understanding the chemistry at a fundamental level. This book serves as a reference book for researchers by providing fundamental understanding of many nanoscopic materials.
This book presents selected contributions to the 16th International Conference on Global Research and Education Inter-Academia 2017 hosted by Alexandru Ioan Cuza University of Iași, Romania from 25 to 28 September 2017. It is the third volume in the series, following the editions from 2015 and 2016. Fundamental and applied research in natural sciences have led to crucial developments in the ongoing 4th global industrial revolution, in the course of which information technology has become deeply embedded in industrial management, research and innovation – and just as deeply in education and everyday life. Materials science and nanotechnology, plasma and solid state physics, photonics, electrical and electronic engineering, robotics and metrology, signal processing, e-learning, intelligent and soft computing have long since been central research priorities for the Inter-Academia Community (I-AC) – a body comprising 14 universities and research institutes from Japan and Central/East-European countries that agreed, in 2002, to coordinate their research and education programs so as to better address today’s challenges. The book is intended for use in academic, government, and industrial R&D departments as a reference tool in research and technology education. The 42 peer-reviewed papers were written by more than 119 leading scientists from 14 countries, most of them affiliated to the I-AC.
The first international symposium on the subject "The Physics and Chemistry of Si02 and the Si-Si02 Interface," organized in association with the Electrochemical Society, Inc. , was held in Atlanta, Georgia on May 15- 20, 1988. This symposium contained sixty papers and was so successful that the sponsoring divisions decided to schedule it on a regular basis every four years. Thus, the second symposium on "The Physics and Chemistry of Si02 and the Si02 Interface was held May 18-21, 1992 in St. Louis, Missouri, again sponsored by the Electronics and Dielectrics Science and Technology Divisions of The Electrochemical Society. This volume contains manuscripts of most of the fifty nine papers presented at the 1992 symposium, and is divided into eight chapters - approximating the organization of the symposium. Each chapter is preceded with an introduction by the session organizers. It is appropriate to provide a general assessment of the current status and understanding of the physics and chemistry of Si02 and the Si02 interface before proceeding with a brief overview of the individual chapters. Semiconductor devices have continued to scale down in both horizontal and vertical dimensions. This has resulted in thinner gate and field oxides as well as much closer spacing of individual device features. As a result, surface condition, native oxide composition, and cleaning and impurity effects now provide a much more significant contribution to the properties of oxides and their interfaces.
This is the first complete overview of the present state of the art of flexible barrier materials such as textile, paper and leather, including methods for barrier evaluation. It will be of interest to readers in industries, consumers, and members of the scientific community. The scope of the field is clearly delineated here for the first time, and it deals with a number of specific topics such as barrier to fire and antibacterial properties.
This book introduces readers to fundamental information on phosphor and quantum dots. It comprehensively reviews the latest research advances in and applications of fluoride phosphors, oxide phosphors, nitridosilicate phosphors and various quantum dot materials. Phosphors and phosphor-based quantum dot materials have recently gained considerable scientific interest due to their wide range of applications in lighting, displays, medical and telecommunication technologies. This work will be of great interest to researchers and graduate students in materials sciences and chemistry who wish to learn more about the principles, synthesis and analysis of phosphors and quantum dot materials.
This book discusses various aspects of different bulk TSO single crystals in terms of thermodynamics; bulk crystal growth using diverse techniques involving gas phase, solution, and melt; and the resulting crystal size, appearance, and structural quality as well as the fundamental properties that were gathered from bulk single crystals. It presents experimental results accompanied by theoretical results, such as band structure and native defects. Combinations of various bulk single crystals along with their properties show great promise in practical device functionality and fabrication. Many TSO-based devices have already been demonstrated in several technical areas, including electronics, optoelectronics, and photovoltaics as well as sensing devices. The book is the first of its kind that brings together a variety of bulk single crystals of scientifically and technically important TSOs along with their properties, which may result in novel devices with unique functionalities.
