Which mobility models are available in Lumerical? Which tunneling models are available?

      In TWLM these effects are included through various recombination rates in the laser rate equations. We do have another solver called CHARGE, which is a 2D/3D finite element drift diffusion solver with standard mobility and tunneling models. While CHARGE does not model laser emission physically, it does have a stimulated recombination model and the parameters of this model can be populated from the TWLM simulation. Find more details about the model in section Stimulated recombination here: nThe user can plot IV curves, 2D/3D current density, electric field, and others. Here's an example of using CHARGE for LIV laser simulation.nnQuestion migrated from the Lumerical Knowledge Exchangen
