Compound Semiconductors for HighTemperature Electronic ApplicationsThis work was sponsored by the U.S. Department of Energy under Contract DEAC0476DPOO789 for Office of Basic Energy Sciences, Division of Engineering, Mathematical and Geosciences.

Compound semiconductor technology is reviewed as it relates to high-temperature electronic device applications. The electrical requirements of majority and minority carrier device types are examined and sixcompound semiconductor materials are presented which are capable of operation above 300°C. The state of the technological development of each of these materials is then reviewed, and several potential application areas of compound semiconductors are suggested. Finally, the high-temperature characteristics of devices fabricated in four of these chemical systems are displayed, and conclusions are drawn on the near term commercialization of this technology.
