The barrier potential can be expressed using the formula:
Let us know the terms used in the formula:
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.
