    The depletion layer in the P-N junction region is caused by  [CBSE PMT 1994]

    A)            Drift of holes

    B)            Diffusion of charge carriers

    C)            Migration of impurity ions

    D)            Drift of electrons

    Correct Answer: B

    Solution :

               Due to the large concentration of electrons in N-side and holes in P-side, they diffuses from their own side to other side. Hence depletion region produces.
