Abstract :
We have begun development of Ge power diodes and transistor for operation at cryogenic temperatures, down to ∼ 20 K (∼ -250°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 ∼ 400 V, as well as insulated-gate FETs, both operating down to ∼ 4 K (∼ minus; 270°C).
