WebNov 8, 2024 · Properties of p-n Junction in Forward Bias The externally applied voltage in forward bias sets up an electric field in the opposite direction to that of the potential barrier. As the value of external voltage increases from 0 to cut-in voltage, the width of the potential barrier decreases. 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.
