Q. 3 IMPATT DIODES, SCHOTTKY BARRIER DIODES, PIN DIODES
Explanation by: Mr. Dubey
a reverse bias voltage exceeding the breakdown voltage is applied to an impatt diode, a high electric field appears across the n+ p junction. this high field imparts sufficient energy to the holes and also to valence electrons to raise themselves to the conduction band. this results in avalanche multiplication of electron hole pair.
