Webb30 okt. 2024 · When the p–n junction is forward-biased, electric charge flows freely due to reduced resistance of the p–n junction. When the p–n junction is reverse-biased, … WebbfWhen a PN junction of a semiconductor material is reverse polarization, a voltage is applied that has the ability to cause electrons and holes to flow in opposite directions across the junction region. This is possible due to the presence of a depletion zone that forms in the junction region, which behaves as a barrier to the
