Consider an open-circuited p-n junction in thermal equilibrium. Let $J_{p, d r i f t}$ and $J_{p, d i f f}$ be the hole drift and diffusion current densities, respectively, and let $J_{n, d r i f t}$ and $J_{n, d i f f}$ be the corresponding electron current densities. Of the following equalities, mark false,at all points in the p-n junction structure.

J_{n, d r i f t}

= -

Solution

The correct option is C $J_{n, d r i f t}$ = $J_{n, d i f f}$ and $J_{p, d r i f t} = J_{p, d i f f}$
electron diffusion and drift are not equal in pn junction.same holds for holes drift and diffusuion velocities
