WebShockley-Read-Hall recombination can be considered as the independent capture of electrons and holes by a crystal defect or impurity via interactions with lattice vibrations. Auger recombination is a three-carrier process that involves an electron and a hole recombining across the band gap with the excess energy of that recombination going to a … Web12 Apr 2024 · Both Auger recombination and bulk Shockley-Read-Hall (SRH) recombination processes are negligible, due to the elimination of a highly doped region (i.e., dopant-free contact device). The photocarriers generated beyond 10 μm are at depths within their typical diffusion length (hundreds of micrometers) in relation to the collecting surface.
