Question

what is the role of potential barrier in a diode.how is it formed in a diode?​

Answer 1

Explanation:

Barrier Potential: The electric field formed in the depletion region acts as a barrier. External energy must be applied to get the electrons to move across the barrier of the electric field. The potential difference required to move the electrons through the electric field is called the barrier potential.
