Semiconductor Electronics Materials Devices And Simple Circuits Ques 42
42. Barrier potential of a $p-n$ junction diode does not depend on
[2003]
(a) doping density
(b) diode design
(c) temperature
(d) forward bias
Show Answer
Answer:
Correct Answer: 42.(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.
