The barrier potential of a p-n junction depends on:

1. type of semiconductor material
2. amount of doping
3. temperature
4. (A) and (B) only

Correct answer: (A) and (B) only

Solution

The barrier potential of a p-n junction depends on the type of semiconductor material, the amount of doping, and the temperature. Since option D includes both (A) and (B), it is the correct choice.
