Recombination Mechanisms

Describes the processes by which electron-hole pairs are annihilated, including direct recombination (radiative) and Shockley-Read-Hall (SRH) recombination via traps.

The statement of the theorem

The total recombination rate

R

(pairs per unit volume per unit time) is modeled as the sum of various mechanisms:

R = R_{direct} + R_{SRH} + R_{Auger}

where

R_{direct}

is the radiative recombination rate,

R_{SRH}

is the Shockley-Read-Hall rate mediated by trap states, and

R_{Auger}

accounts for multi-particle recombination effects.
