Wide Bandgap Semiconductor Power Devices: Materials, Physics, Design and Applications provides readers with a single resource on why these devices are superior to existing silicon devices. The book lays the groundwork for an understanding of an array of applications and anticipated benefits in energy savings. Authored by the Founder of the Power Semiconductor Research Center at North Carolina State University (and creator of the IGBT device), Dr. B. Jayant Baliga is one of the highest regarded experts in the field. He thus leads this team who comprehensively review the materials, device physics, design considerations and relevant applications discussed.
- Comprehensively covers power electronic devices, including materials (both gallium nitride and silicon carbide), physics, design considerations, and the most promising applications
- Addresses the key challenges towards the realization of wide bandgap power electronic devices, including materials defects, performance and reliability
- Provides the benefits of wide bandgap semiconductors, including opportunities for cost reduction and social impact

Professor Baliga obtained his Bachelor of Technology degree in 1969 from the Indian Institute of Technology, Madras, India. He was the recipient of the Philips India Medal and the Special Merit Medal (as Valedictorian) at I.I.T, Madras. He obtained his Masters and Ph.D. degrees from Rensselaer Polytechnic Institute, Troy, NY, in 1971 and 1974, respectively. His thesis work involved Gallium Arsenide diffusion mechanisms and pioneering work on the growth of InAs and GaInAs layers using Organometallic CVD techniques. At R.P.I., he was the recipient of the IBM Fellowship in 1972 and the Allen B. Dumont Prize in 1974.
From 1974 to 1988, Dr. Baliga performed research and directed a group of 40 scientists at the General Electric Research and Development Center in Schenectady, NY, in the area of Power Semiconductor Devices and High Voltage Integrated Circuits. During this time, he pioneered the concept of combining MOS and Bipolar physics to create a new family of discrete devices. He is the inventor of the IGBT which is now in production by many International Semiconductor companies. For his work, Scientific American Magazine named him one of the 'Eight heroes of the semiconductor revolution' in their 1997 special issue commemorating the Solid-State Century. Dr. Baliga is also the originator of the concept of merging Schottky and p-n junction physics to create a new family of JBS power rectifiers that are commercially available from various companies.
In August 1988, Dr. Baliga joined the faculty of the Department of Electrical and Computer Engineering at North Carolina State University, Raleigh, North Carolina, as a Full Professor. At NCSU, in 1991 he established an international center called the Power Semiconductor Research Center (PSRC) for research in the area of power semiconductor devices and high voltage integrated circuits, and has served as its Founding Director. In 1997, in recognition of his contributions to NCSU, he was given the highest university faculty rank of Distinguished University Professor of Electrical Engineering. In 2008, Professor Baliga was a key member of an NCSU team - partnered with four other universities - that was successful in being granted an Engineering Research Center from the National Science Foundation for the development of micro-grids that allow integration of renewable energy sources.
In 2010, Dr. Baliga was inducted into the Engineering Design Magazine's "Engineering Hall of Fame for his invention, development, and commercialization of the Insulated Gate Bipolar Transistor (IGBT), joining well known luminaries (e.g. Edison, Tesla, and Marconi) in the electrical engineering field. The award announcement states: "While working at General Electric in the late 1970s, Baliga conceived the idea of a functional integration of MOS technology and bipolar physics that directly led to the IGBT's development. it remains undeniable that Baliga's vision and leadership played a critical role in moving the IGBT from a paper-based concept to a viable product with many practical applications.
Professor Baliga has received numerous awards in recognition for his contributions to semiconductor devices. These include two IR 100 awards (1983, 1984), the Dushman and Coolidge Awards at GE (1983), and being selected among the 100 Brightest Young Scientists in America by Science Digest Magazine (1984), and, on October 21, 2011, President Obama personally presented Dr. B. Jayant Baliga with the National Medal of Technology and Innovation, the highest form of recognition given by the United States Government to an Engineer, in a ceremony at the White House. Dr. Baliga's award citation reads: For development and commercialization of the Insulated Gate Bipolar Transistor and other power semiconductor devices that are extensively used in transportation, lighting, medicine, defense, and renewable energy generation systems.
