Question

The width of the space charge region at a p-n junction is reduced by applying a voltage bias over the p-n junction. What is the correct statement on both the bias voltage and the p-n junction? The voltage is a forward bias and the diffusion of the majority charge carriers becomes more dominant. The voltage is a reverse bias and the diffusion of the majority charge carriers becomes more dominant. The voltage is a forward bias and the drift of the minority charge carriers becomes more dominant. The voltage is a reverse bias and the drift of the minority charge carriers becomes more dominant.
