Web23 Aug 2024 · Those are the Shockley-Read-Hall (SRH) process and auger recombination. SRH is recombination through atomic trap's in the lattice. These traps are caused by impurities or defects within the lattice which create intermediate bands within the band gap. This converts the electron/hole energy into phonons (lattice vibrations/heat).
