Figure 23: Shifting the electrons as the density of states over~ω(energy of photons)7.2 Electronic Band Structure Calculations
In this section the band structure is calculated. In the sections before this was done for the free
electron gas (1d, 2d, 3d), now the electrons are put in a periodic potential and the properties are
evaluated with these methods:
- Empty lattice approximation
- Central equations
- Tight binding
