is the w:conduction band, indicates the quasi-w:fermi energy levels, is the intrinsic Fermi level of the undoped semiconductor, and is the w:valence band. This band alignment is due to the biasing conditions that correspond with forward-active mode; forward bias on the emitter-base junction and reverse bias on the base-collector junction.
Band diagram for NPN transistor at equilibrium Band diagram for NPN transistor in active mode, showing injection of electrons from emitter to base, and their overshoot into the collector BJTs can be thought of as two diodes (p–n junctions) sharing a common region that minority carriers can move through.
Energy band diagram of a simple bipolar junction transistor under equilibrium showing electron energy versus position. The depletion regions of the emitter-base and base-collector junctions are marked. <math>E_c</math> is the conduction band
A schematic diagram of the Ebers-Moll models of a PNP BJT. The base, collector and emitter currents are I B, I C and I E, the common-base forward and reverse current gains are α F and α R, and the collector and emitter diode currents are I CD and I ED.

Band diagram for Schottky barrier at equilibrium Band diagram for semiconductor heterojunction at equilibrium. In solid-state physics of semiconductors, a band diagram is a diagram plotting various key electron energy levels (Fermi level and nearby energy band edges) as a function of some spatial dimension, which is often denoted x.

PNP transistor symbol with case (IEEE 315). Note: A little confusing on the BJT page, because the NPN is drawn with Collector (C) on the top, while here it is drawn on the bottom. Date: 11 November 2007: Source: Own work: Author: Zedh: Other versions.svg:
