A three-band model and … Websemiconductor, Shockley-Read-Hall (or thermal recombination), radiative recombination, and Auger recombination. The three have similarities and differences, but once we get quantitative, the recombination rate equations for all three can be expressed in identical fashion. Topics such as low level injection and excess carriers are also explained.

Web1 Sep 1995 · We calculated the steady‐state recombination rate for two coupled defect levels and implemented the model into a device simulator. This model generalizes the familiar single‐level Shockley–Read–Hall (SRH) formula. If the intercenter transition probability vanishes, it reduces to the sum of two individual SRH rates, which are only …
