Ultra-wide Bandgap Semiconductors (UWBG) covers the most recent progress in UWBG materials, including sections on high-Al-content AlGaN, diamond, B-Ga2O3, and boron nitrides. The coverage of these materials is comprehensive, addressing materials growth, physics properties, doping, device design, fabrication and performance. The most relevant and important applications are covered, including power electronics, RF electronics and DUV optoelectronics. There is also a chapter on novel structures based on UWBG, such as the heterojunctions, the low-dimensional structures, and their devices. This book is ideal for materials scientists and engineers in academia and R&D searching for materials superior to silicon carbide and gallium nitride.

Authors
Meiyong Liao Principal Researcher, National Institute for Materials Science (NIMS), Japan.
Meiyong Liao received his doctor of Materials Science at the Institute for Semiconductors, Chinese Academy of Science (Beijing, China) 2002. For two years he was a visiting researcher at Kyoto University, Japan. Then, he joined the Diamond Research Group at the National Institute for Materials Science, Tsukuba in 2004. Presently, he works as a principal researcher at NIMS on the topics of semiconducting diamond growth, device physics, and applications. He developed the world-record DUV diamond photodetector and proposed the photoconductive mechanism of diamond. He also proposed a novel type normally-off diamond transistor. He pioneered the semiconductor single crystal diamond MEMS/NEMS and demonstrated the SCD NEMS switch for the first time. He has been engaged in CVD diamond research for more than 15 years and published more than 150 peer-reviewed journal papers with more than 6000 citations.
Bo Shen The Edelman-Jarislowsky Professor of Surgical Sciences , Professor of Medicine and Surgical Sciences (in Surgery), Director of Interventional Inflammatory Bowel Disease , Vice Chair of Innovation in Medicine & Surgery , Herbert Irving Pavilion, Columbia University Vagelos College of Physicians and Surgeons, Department of Surgery.
Dr. Shen is the head and medical director of the IBD Center at Columbia. He is also the Vice Chair for Innovation in Medicine and Surgery and a Professor of Medicine (in Surgery). He is one of the world's pre-eminent leaders in interventional inflammatory bowel disease (IBD) due to his specialized expertise in treating a wide range of pouch-related disorders. In addition to pouchitis and pouch diseases, Dr. Shen specializes in IBD, GI endoscopy (including endoscopic pouch procedures), and imaging technology. Dr. Shen is known as a pioneer in interventional treatment for IBD - this includes postponing or eliminating the need for surgery in some cases.
Zhanguo Wang Professor, Institute of Semiconductors, Chinese Academy of Science, China.
Zhanguo Wang is a semiconductor materials physicist, and Research Professor in the Institute of Semiconductors, Chinese Academy of Sciences. Zhanguo Wang was elected as a Member of the Chinese Academy of Sciences in 1995. In the early 1960s, Wang was engaged in studies on radiation effects of silicon solar cells for satellites and the optical and electrical properties of semiconductor materials. From 1980, his main interests were on the deep level physics and spectrum physics of semiconductors. He and his colleagues developed a new method to identify whether the two deep levels within a band gap are coupled or not, thus solving the long existing fundamental question of gold-related donor and acceptor in Si, and A and B deep levels in LPE GaAs. He suggested a model of deep level broadening and PL spectrum splitting in semiconductor alloys. In 1986, he joined Professor Lin Lanying's group, and the GaAs single crystal was successfully grown from the melt in space for the first time. In 1993, he proposed a multi-level compensation model and new criteria of electrical compensation for undoped SI-GaAs, which can not only explain the GaAs conductivity but also provide a clue for improving the quality of this material. Recently, he and his co-workers are working on low dimensional semiconductor materials (quantum well, quantum wires and quantum dots etc) growth and quantum devices fabrication. His group has also been engaged in the research of wide-band gap semiconductors of III-nitrides, ZnO, diamond, BN, etc. He has published more than 400 peer-reviewed journal papers and is the author of several academic books.
