Reply To: free carrier absorption consideration for photodiode simulation

[Guilin Sun]

Yes I agree that photons are not 100% converted to n-p carriers. For excitons it can be  modeld by such as radiative recombination. If you do not want such excitons, you can simply ignore such recommbination. Such recombinations are material based. so it is possible to limit the aear of exitons with proper material properties.

Please note that the simulation accuracy can only be as accurate as your simulation model, with infinitely small mesh.
