2. Light emission and absorption mechanisms in semiconductors
This section focuses on the generation and recombination of carriers in a semiconductor material.
2.1 Charge density in a semiconductor material
For each type of semiconductor material, extrinsic or intrinsic (i.e., doped or not intentionally doped), in the state of thermodynamic equilibrium, the concentrations of electrons n 0 (1) and holes p 0 (2) are defined from the density of states in the valence band N v and in the conduction band N c...
