Pn minority's
WebSemiconductors contain majority and minority carriers. The more abundant charge carriers are the majority carriers; the less abundant are the minority carriers. The equilibrium carrier concentration can be increased through doping. The total number of carriers in the conduction and valence band is called the equilibrium carrier concentration. WebReverse Biased PN Junction Diode. When a diode is connected in a Reverse Bias condition, a positive voltage is applied to the N-type material and a negative voltage is applied to the P-type material.. The positive voltage applied to the N-type material attracts electrons towards the positive electrode and away from the junction, while the holes in the P-type end are …
