Electrical Conductivity of user defined Doped Semiconductor

I have a grated doping profile in several regions of my model defined using the Analytic Doping Model in the Semiconductor Module. I'm now trying to use the RF module to do an eigenvalue sweep, but I need the electrical conductivity signma. The conductivity is of course a function of the doping. How can I specify this in the property list for the materials, or provide a grated electrical conductivity separately to override each region individually? Any help is appreciated!

You can always use the reserved variables x,y and z to use your own functions to define conductivity distributions if they can be neatily described by analytic functions. You can also import data from another simulation using for example withsol('sol1', emw.Ez) if you want to import the electric field in the Z direction. I don't know what the variable names are of semiconductor physics. In any case, as long as you use the same mesh (haven't tried it with two different meshes yet but i think it can work) you can directly include results from another simulation into your material properties field. if those material properties are already defined for your Semiconductor simulation you can add in your RF analysis a new wave equation volume node applied to the relevant region and then specify a user defined conductivity using the previously mentioned method.
