	Radiative recombination takes place when an electron in the conduction band relaxes to the valence band via the emission of a photon. Auger recombination needs an interaction between at least two electrons in the conduction band, so the first electron recombines with a hole and transfers its energy to the second electron. Instead of an interaction between two electrons, Auger recombination can occur through an interaction between two holes in the valence band. The first hole recombines with an electron and transfers its energy to the second hole.
