Question

The motion of charge carriers, across the potential barrier, in a forward and reverse biased p–n junction, is due, respectively, to

(1) Drift, diffusion

(2) Diffusion, drift

(3) Drift in both cases

(4) Diffusion in both cases

Answer 1

Correct option: (2) Diffusion, drift

Explanation:

The charge carriers, diffuse across the junction during the forward biasing of a p–n junction. During reverse biasing, the motion of charge carriers, is due to their drift.
