Why a contact difference of potential exist in PN junction ?
Dear student,
The difference helps minority carriers to drift across the junction and discourages the diffusion of any more majority carriers across the junction.The significance of this potential across the junction is that it opposes both the flow of holes and electrons across the junction.
