Shockley hall read recombination
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. WebAbstract. The statistics of the recombination of holes and electrons in semiconductors is analyzed on the basis of a model in which the recombination occurs through the …
