    A potential barrier of \[0.50\,V\] exists across a p-n junction. If the depletion region is \[5.0\times {{10}^{-7}}m\]wide, the intensity of the electric field in this region is

    A)  \[1.0\times {{10}^{6}}\,V/m\]

    B)  \[1.0\times {{10}^{5}}\,V/m\]

    C)  \[2.0\times {{10}^{5}}\,V/m\]

    D)  \[2.0\times {{10}^{6}}\,V/m\]

    Correct Answer: A

    Solution :

    [a] \[E=\frac{V}{d}=\frac{0.50}{5\times {{10}^{-7}}}V/m=1.0\times {{10}^{6}}V/m\]
