Energy Bands in CrystalsWe are now in a position to make additional important statements which contribute considerably to the understanding of the properties of crystals. For this we plot the energy versus the momentum of the electrons or, because of (4.8), versus the wave vector .. As before we first discuss the one-dimensional case.

Semiconductors, finally, represent in some respect a position in between metals and insulators. We mentioned in Chapter 6 that semiconductors have, at low temperatures, a completely filled valence band and a narrow gap between this an
