10What do you mean by the contact potential? Give a schematic of a p-n Junction by illustrating:
- (a) Potential difference V, resulting from the positive donor ions in the n-side of the depletion layer and the negative acceptor ions in the p-side of the depletion layer.
- (b) Potential energy barrier faced by the majority charge carriers (electrons) in the n-side of the diode as they attempt to cross the junction.
- (c) Potential energy barrier faced by the majority side of the diode as they attempt to cross the junction.
A worked answer is on its wayMeanwhile, read the Physics notes for this topic.
