Write the two processes that take place in the formation of a p-n junction. Explain with the help of a diagram, the function of depletion region and barrier potential in a p-n junction.

With reference to a semiconductor diode, define the terms .depletion region. and .potential barrier.. How will the width of depletion region change during reverse biasing?

What is meant by depletion region in a junction diode? How is this region formed?

A zener diode has a contact potential of 1 V in the absence of biasing. It undergoes Zener breakdown for an electric field of 10^(6) V/m at the depletion region of p-n junction. If the width of the depletion region is 2.5 mu m, what should be the reverse biased potential for the Zener breakdown to occur ?
