Forward biased pn junction

Cross-sectional schematic of a forward-biased pn junction, with the p region colored pink-red on one side and the n region blue on the other. An external voltage source is connected so the positive terminal is on the p side and the negative terminal is on the n side. The central depletion region is drawn narrower than normal, and the potential barrier at the interface is reduced. A forward-direction arrow or polarity cue may indicate current-driving direction across the junction.
