PN junction |Formation of depletion layer

If a PN junction diode of depletion layer width W and barrier height V_(0) is forward biased, then

Explain the formation of depletion layer and potential barrier in p-n junction. Draw the circuit diagram of a half wave rectifier and explain its working.

In revers bias pn-junction diode depletion layer width
