Answer Posted / sudhanshu
Drift current depends on the electric field applied: if
there's no electric field, there's no drift current.
Diffusion current occurs even though there isn't an
electric field applied to the semiconductor. It does not
have E as one of its parameters. The constants it does
depend on are Dp and Dn, and +q and -q, for holes and
electrons respectively.
