We say that under equilibrium, no further movement of majority carriers takes place due to the immobile ions or the electric field or built in potential stops it.
But in many cases and videos I seen, they say that diffusion current balances the drift current, resulting in zero current. Now according to me, the drift current in a p-n junction is due to minority carriers which are less, and then we should get a current because of it.
But many texts says the drift current direction is opposite to the diffusion current, but when majority charge carriers are not allowed to move further then how can one argue this that diffusion counters drift when diffusion in general is not happening only? There must be some minority current or am I missing something?
