Abstract : The need for electronic devices which will reliable operate in the temperature range from 400 to 600 deg C has made it essential to look beyond conventional electronic materials such as silicon or gallium arsenide. Devices based on these materials are presently able to meet a limited number of elevated temperature demands, but only with the added cost and complexity of an environmental cooling system. Sensors and control devices mounted on or in aircraft engines, operating at temperatures of 500 to 600 deg C for periods of up to 100 hours, are needed for increased design engineering feedback, and diminished testing and maintenance costs. Integration of the additional weight of the required cooling system for Si devices is already a substantial impediment to increased performance in supersonic aircraft. Electronics to be used in planetary space probes must be capable of extended operation at temperatures above 500 deg C. Consequently, the environmental cooling system for space based vehicles already accounts for over one-half of current launch vehicle payloads. The development of devices intended for operation in high temperature environments would not only meet these existing needs, but would allow many new applications of distributed feedback control....
