# What happen to the electric field in depletion region of a $p-n$ junction diode in forward bias vs a no bias condition?

Does the electric field strength within the depletion region decrease as a result of a decrease in the depletion width due to forward bias vs no bias condition?

Does this electric field strength whether or not is affected by different bias condition contribute to the change in the barrier potential somehow if all other factor remains the same (i.e.: temperature, acceptor concentration, donor concentration same element)?

• This generally is shown clearly in all intro texts that I know of. Yes, the field in the depletion layer changes with applied bias. Could you clarify your question? Apr 16 '20 at 17:00
