Expression For Barrier Potential In P-n Junction Diode

The barrier potential can be expressed using the formula:

Let us know the terms used in the formula:

P-n Junction Diode

P-n junction diode - It is a semiconducting device that manages the flow of electric current in a circuit.

It has a positive (p) side and a negative (n) side and is hence called a p-n junction diode.

Usually, in a p-n junction the value of barrier potential is typically 0.3-0.7V depending upon the material used.
