the holes from the n-type semiconductor are pushed towards the junction by the positive terminal of the battery. This movement of electrons and holes constitutes a current called reverse saturation current.??The term?saturation?refers to the fact that it reaches its maximum value very quickly and does not change significantly with increase in reverse bias potential.
52) When a P- N junction is reversed biased, the flow of current across the junction is mainly due to
Answer is:
diffusion of charge carriers

ALPHA (?):?It is a large signal current gain in common base configuration. It is the ratio of collector current (output current) to the emitter current (input current).It is a current gain in CB amplifier and it indicates that the amount of emitter current reaching to collector. Its value is unity ideally and practically less than unity. Beta (?): It is a current gain factor in the common emitter configuration. It is the ration of collector current (output current) to base current (output current).
