In case a pn-junction is forward biased:

WebUnder the forward bias, the electrons in the p-type region move collectively towards the positive terminal. This includes the electrons in the p-surface but it is supplanted immediately after it left by electrons from the n-region. Therefore, p-region gained equal electrons as it has lost so no charge difference. WebSolution for the case of pn junction of the same material, ...
