Depletion Region And Barrier Electric Field

In a zener diode, the reverse bias voltage is 3 V and the width of the depletion region is 300 A the electric field intensity will be ____ (V)/(cm)

The depletion region is

The knee voltage of a p-n junction diode is 0.8 V and the width of the depletion layer is 2muA . The electric field in the depletion layer is

Q6.When "p" - "n" junction diode is forward biased,then (a)the depletion region is reduced and barrier height is increased (b) the depletion region is widened and barrier height is reduced (c)both the depletion region and barrier height are reduced (d) both the depletion region and barrier height are increased

Explain the term depletion region and potential barrier for a p-n junction.

Explain with the help of a diagram, how depletion region and potential barrier are formed in a junction diode. If a small voltage is applied to a p-n junction diode how will the barrier potential be affected when it is (i) forward biased and (ii) reverse biased?
