WebJul 5, 2024 · A p-n junction is forward biased by the voltage source. The motions of the holes and electrons in the p-n junction diode are different under forward bias than they are under reverse bias. As before, the holes in the p-type material experience a diffusive … Reverse bias. Under reverse bias, the n side is held at a higher voltage than the … WebMar 18, 2013 · The electrons and holes do not diffuse/combine together and disappear! When the p-n junction is reverse biased, the barrier resistance is increased, so little or no electron current flows. When forward biased, the barrier resistance is decreased, and a larger electron current flows. This property is used to make diode rectifiers.
