The analysis of Bloch waves given in the previous chapter is closely related to the classic analysis of waves that you’ve seen in condensed-matter physics or semiconductor theory. In semiconductors in particular, we often talk of band diagrams and indirect or direct band gaps. We use terms like conduction bands, valence bands, and Brillouin-zone boundaries (BZBs). We visualize these quantities by drawing diagrams of E(k), the electron energy (which is a function of k) versus k, the wave vector.

- As in Chapter 14 we follow the treatment of Hirsch et al. as extended and illustrated by Metherell. For anyone familiar with MathematicaTM (or the corresponding) MatLab it would be an interesting challenge to construct (and share) notebooks for these diagrams.Google Scholar
