8. Light and matter
1. Isolated atoms
Boltzmann distribution: $$ \frac{n_i}{n_j} = \frac{g_i}{g_j} e^{(E_j-E_i) / (kT)} $$
where $g$ is the number of distinct quantum mechanical states at a specific energy level.
2. Isolated molecules
3. Solid-state crystals
3.1 Bonds and bands
3.2 Conduction
3.3 Semiconductors
$$ P(T,E) = \frac{1}{1+e^{(E-E_F) / (kT)}} $$
$$ n_e (T,E) = P(T,E) S(E) $$
where $S$ is the number density of available states at an energy $E$.
4. Photoconductors
5. MOS capacitors
6. The p-n junction
