1 Answer

Answer :

Ans: (c)

When a pn-junction is formed, there will be diffusion of carries across the junctions followed by recombination, and the creation of a depletion layer across which a barrier potential is established, which will prevent further diffusion of carries across the junction, leading to equilibrium
