PN Junction Diode: Graph, Working Principle, Properties, Uses

WebbWhen a p-n junction is being formed, holes diffuse from the p-side to the n-side (p→n) while electrons diffuse from the n-side to the p-side (n→p). This happens due to the concentration gradient across p and n sides. … WebbThe P region is physically thin. If the second PN junction (between base and emitter) is forward-biased, electrons can now be injected into the base P region from the emitter, because charge neutrality in the P region is maintained by current from the base contact. cs bridgehead\u0027s
