I am trying to model the optical properties of vertical silicon nanowires. I have created a model in Lumerical FDTD which does not behave the way my lab experiments do… The geometry is very simple, so I am confident that the simulation design is correct, but the results just don’t agree with experimental data.
I’m wondering if the material properties are the cause of the difference. In my lab we use doped silicon, but the Palik Si file is, I believe, undoped Si. Could this possibly be the cause of the difference? I think the only place this could manifest would be in the imaginary part of the refractive index.
Does anyone have any experience modeling doped silicon nanostructures in Lumerical FDTD?
