PREFACE

Interest in wide-bandgap semiconductors for high-power/high-temperature electronicsremains prominent. For such applications, SiC is by far the most mature semiconductormaterial; however, GaN and diamond have also become prime candidates. From a purelymaterial property perspective, diamond has several advantages over the other two materials;however, producing large single-crystals as well as the inability to achieve n-type doping havelimited device fabrication. For GaN, recent advances in crystal growth and processingcapabilities, as well as excellent transport properties, have yielded a great deal of devicedevelopment, yet thermal conduction remains an issue. SiC has excellent thermal conductivity,high-breakdown voltages, and well-developed substrates and processing techniques.

The "Wide-Bandgap Electronic Devices" symposium, held April 24-27 at the 2000 MRSSpring Meeting in San Francisco, California, dealt with a wide range of technical activity in thearea of wide-bandgap high-power/high-temperature electronic devices. The 102 paperspresented in this symposium covered topics including the fabrication and performance of GaN-based and SiC-based devices as well as issues related to growth, characterization, and processingof wide-bandgap materials. Several summaries of the current status of high-power/high-temperature-based GaN and SiC electronic devices were given.
