Abstract

Electrons in the conduction band and holes in the valence band behave as free particles, but their distribution among the available energy levels, when in thermal equilibrium with the lattice, obeys Fermi-Dirac statistics [5.1]. The function giving the occupancy of the levels, often called the Fermi function, is
$$n_S /g_S = 1/\left\{ {1 + \exp \left[ {\left( {E_S - E_F } \right)/k_B T} \right]} \right\},$$
(5.1)
