Physics Question on Semiconductor electronics: materials, devices and simple circuits
Barrier potential of a p-n junction diode does not depend on:
A
diode design
B
temperature
C
forward bias
D
doping density
Answer
diode design
Explanation
Solution
The barrier potential of a p-n junction diode is primarily determined by the difference in work functions between the p-type and n-type materials and the intrinsic properties of the materials themselves. It does not depend on diode design. On the other hand, temperature, doping density, and forward bias voltage can influence the barrier potential.
So, the correct option is (A): diode design
