Si-SiGe Base Bipolar Band Diagram A Si-SiGe base bipolar band diagram is a graphical representation of the energy bands in a silicon-germanium (SiGe) bipolar junction transistor (BJT). It shows the conduction band, valence band, and the quasi-Fermi levels for electrons and holes in the emitter, base, and collector regions of the transistor. The band diagram …
