Silicon carbide is known to have been investigated since 1907 when Captain H J Round demonstrated yellow and blue emission by applying bias between a metal needle and an Si C crystal. The potential of using Si C in semiconductor electronics was already recognized half a century ago. Despite its well-known properties, it has taken a few decades to overcome the exceptional technological difficulties of getting silicon carbide material to reach device quality and travel the road from basic research to commercialization.This second of two volumes reviews four important additional areas: the growth of Si C substrates; the deep defects in different Si C polytypes, which after many years of research still define the properties of bulk Si C and the performance and reliability of Si C devices; recent work on Si C JFETs; and the complex and controversial issues important for bipolar devices.Recognized leaders in the field, the contributors to this volume provide up-to-date reviews of further state-of-the-art areas in Si C technology and materials and device research.
