A Zenor diode has a contact potential of 1 V in the absence of biasing. It undergoes Zenor breakdown for an electric field of 10⁶ V/m at the depletion region of p-n junction. If the width of the depletion region is 2.5 μm, what should be the reverse biased potential for the Zenor breakdown to occur?

Options

(a) 3.5 V
(b) 2.5 V
(c) 1.5 V
(d) 0.5 V

Correct Answer:

2.5 V
