The aim of this special collection of peer-reviewed papers is to present recent progress in crystal growth, in the characterization and control of material properties, as well as in other basic research issues concerning silicon carbide (SiC) and other wide-bandgap semiconductors such as group-III nitrides and diamond. The latest research results relevant to wafer production processes, device fabrication technologies and device applications are discussed. These included the latest results in the development and commercialization of advanced devices and circuits used for energy saving, high-voltage switching, high-frequency high-power amplification and high-temperature operation. Work on the growth, characterization and device exploitation of epitaxial graphene was also covered. Evolving industrial products and capabilities were also highlighted.Volume is indexed by Thomson Reuters CPCI-S (WoS).
