In a `p-n` junction diode, the barrier potential opposes diffusion of

P-N junction diodes

In a p-n junction , the barrier potential offers resistance to

In P-N junction, the barrier potential offerse resistance to

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?

In a forward biased p-n junction diode, the potential barrier in the depletion region will be of the form

Explain the two processes involved in the formation of a p-n junction diode. Hence, define the term 'barrier potential'.
