. The dominant mechanisms for motion of charge carriers in forward and reverse biased silicon p-n junctions are :

(a) drift in forward bias, diffusion in reverse bias              (b) diffusion in forward bias, drift in reverse bias

(c) diffusion in both forward and reverse bias                   (d) drift in both forward and reverse bias

 

Best Answer

Drift current flows p-side and diffusion current from n-side to p-side. In an unbiased connection, both currents are equal and opposite, therefore, net current is zero. In forward biasing, drift current is more than the diffusion current and in reverse biasing, diffusion current is more than the drift current.
