Silicon Carbide and Related Materials - 2002: (Volumes 433-436 Materials Science Forum)

Volume is indexed by Thomson Reuters CPCI-S (WoS). Wide-bandgap semiconductors such as SiC, III-V nitrides and related compounds are attracting rapidly increasing attention due to their other, very interesting, physical properties which are often superior in many ways to those of conventional semiconductors. Steady improvements in crystal quality, and improved knowledge concerning their physical properties, are leading to rapid developments in high-power, high-temperature, high-frequency electronics and blue-light emitters.
