Question

Statement I: In a $p-n$ junction with open ends there is no motion of charge carriers.\ Statement II: In a $p-n$ junction with open ends the electric field is varying.

Professor PC Thomas Classes · Answer

(c) : In a $p-n$ junction with open ends, a depletion layer is crcated at the junstion dur to diffusion of majority earriers from one side to another and a constant electric field is set up across the junction and therefore, there is motion of charge carriers in $p-n$ junction due to which depletion layer is created.
