Current power electronics world require semiconductor devices which are capable of highly reliable performances under extreme conditions of voltages and temperature. Wide band gap semiconductors are more suitable in comparison to the traditional semiconductors in such cases. One such semiconductor currently in focus is SiC. This book describes the strucutral, electronic and magnetic properties of SiC. It presents the results of coputational studies of few intrinsic and extrinsic impurities in SiC and their combination too. Many conclusions are found which can throw some light on its...
