A digital-computer program has been used to compare the performance of an n+pp+ silicon avalanche diode with its more conventional p+nn+ complementary junction in IMPATT-oscillator operation. The computer simulation of the former junction predicts a significant improvement of oscillator efficiency (20.1 against 13.9%).
