Abstract | We have begun development of Ge power diodes and transistor for operation at cryogenic temperatures, down to sim; 20 K ( sim; -250 deg;C), for use in spacecraft that will encounter low-temperature environments. Ge devices have advantages over Si devices for such deep cryogenic operation. Our initial development has yielded 10-A diodes with low forward voltage and reverse leakage, and reverse breakdown up to sim; 400 V, as well as insulated-gate FETs, both operating down to sim; 4 K ( sim; minus; 270 deg;C). |
