They extracted the Shockley–Read–Hall (SRH) lifetime, which is the square root of the product of hole and electron carrier lifetimes (t SRH = tt pn), by ana-lyzing the … 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.
