(C) In an unbiased $p-n$ junction,diffusion of charge carriers occurs initially. Holes diffuse from the $p$-side to the $n$-side,and electrons diffuse

Vedclass · Accepted Answer

there is an electric field at the junction directed from the $n$-type side to the $p$-type side.

Vedclass · Answer

(C) In an unbiased $p-n$ junction,diffusion of charge carriers occurs initially. Holes diffuse from the $p$-side to the $n$-side,and electrons diffuse from the $n$-side to the $p$-side.This diffusion creates a depletion region at the junction,leaving behind immobile ionized donors on the $n$-side (positive charge) and ionized acceptors on the $p$-side (negative charge).This charge distribution creates an internal electric field directed from the $n$-side (positive) to the $p$-side (negative).This electric field opposes further diffusion,establishing an equilibrium state.
