To easily obtain the zener effect ……..

Options

A. thickness of depletion layer should be increased by increasing the amount of impurity.
B. thickness of depletion layer should be decreased by increasing the amount of impurity.
C. diode should be made as small as possible.
D. none of the above one.

Answer

B

Explanation

thickness of depletion layer should be decreased by increasing the amount of impurity.
If the impurity is high and the width of depletion layer is too low then the electric field in the reverse bias voltage becomes stronger in depletion layer.
