The difference between drift current and diffusion current
is that 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.

Answer / mayank4mail

Drift current-if an electric field is applied to an electron
in free space , it will accelerate the electron in a
straight line from -ve to +ve terminal of the applied voltage.

Answer / saddam hussain

drift current is dependent on external electric field applied
to the semiconductor
but duffusion curent is not.
the life time of drift current is large as compared to the
diffusion current.
