After completing this section, you should be familiar with:
- simple parabolic energy-momentum diagrams (E-k curves)
- the concept of effective mass
- the Fermi sphere
- the ideal parabolic N(E) vs E curve
- the effect of diffraction leading to zone boundaries and band gaps
- the conventional presentation of band diagrams for Si and GaAs
- the reasons for the non-parabolic appearance of DOS curves for nickel and brass.
