I meet the convergence problem when modeling highly doped semiconductor in COMSOL.
What I model is a P-n heterojuction, the concentration of the acceptor is 1e18/cm3, the concentration of
the donor is 3e15/cm3. The result is difficult to converge, even I refined the grids up to 60000!
Does anyone encounter the similar problem?
