(A) When a $P-N$ junction diode is forward-biased,the positive terminal of the external battery is connected to the $P$-region and the negative terminal to the $N$-region.This external electric field opposes the internal electric field of the depletion region.As a result,the width of the depletion layer decreases and the potential barrier height is reduced.Therefore,the potential barrier height decreases in a forward-biased $P-N$ junction diode.

In a forward-biased $P-N$ junction diode,how does the potential barrier behave?
