In a semi conductor junction diode, as the depletion or barrier layer is forward-biased, the layer

remains constant
widens then narrows
คำอธิบาย
In a semiconductor junction diode, applying forward bias to the depletion or barrier layer causes the layer to B. narrow.
This occurs because the applied voltage lowers the potential barrier, facilitating the recombination of charge carriers and reducing the width of the depletion region.
