Technical Caveat: It is common practice when drawing energy band diagrams between two different materials to draw them such that the electron filling level (i.e. Fermi level) is constant from material to material. However, here we take the approach of effectively having a flat vacuum level and allowing the Fermi level to spatially vary. These two approaches are ultimately equivalent but this way has the advantage of not having to discuss issues like the physical meaning of the electrochemical potential and discussing where and why the Fermi level actually rests in a doped semiconductor.
