Show Answer
Answer:
Correct Answer: 35. (b)
Solution:
- (b) Barrier potential does not depend on diode design. Barrier potential depends upon temperature, doping density, and forward biasing.
Potential barrier is the potential difference created across the P-N junction due to the diffusion of electrons and holes.
