Abstract :
The paper reviews the status of SiGe hetero field effect transistors. Essential layer structures for Schottky-, p-n junction-, MOS-gated devices are presented. Mobilities and sheet carrier concentrations are given. Currents, transconductances, frequencies at room- and cryo-temperatures, and high and low frequency noise elucidate the potential of this device concept. Finally, first circuit results are discussed
