Consider an abrupt p-n junction with ND = NA. There are different types of
currents across the junction, namely electron currents, hole currents, drift currents,
and diffusion currents, from p-type to n-type and vice versa.
(a) Which current dominates for forward bias, if Dn Dp and Ln = Lp ?
(b) Which current dominates for reverse bias, if Dn = Dp and Ln = Lp ?
