WebIn fact, this must be the case in order for BJTs to work in common-emitter mode, where the base-collector junction is reverse biased, but the large potential energy change does not prevent, or even significantly hinder, current from flowing through the junction. In this case, the forward biased base-emitter junction provides ("emits") a large ... 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.
