The magnitude of a drift current density is given by J = qnv, where q is the carrier charge, n is the carrier density per unit volume, and v is the carrier drift velocity. q is a physical constant and n is independent of bias. But when an external electric field is applied, the minority charge carriers must surely accelerate and change their drift velocity. How is the drift current of a pn junction not a function of bias?(adsbygoogle = window.adsbygoogle || []).push({});
