Q. In a PN junction diode the barrier potential offers opposition to

A

Minority charge carriers in both regions

B

Majority charge carriers in both regions

C

Holes in N region

D

Electrons in P Region

Solution:

The potential difference required for the electrons to be passed across the electric field is called the potential barrier.
The barrier potential of a P-N junction depends on the type of material, amount of doping and temperature of the semiconductor.
For silicon it is about 0.7V, for germanium, it is about 0.3V.
