Why does the potential show a singularity at the location where the boundary condition changes from Dirichlet to Neumann?
At the gate side, there is a change of boundary condition from Dirichlet to Neumann as we move from the gate to the insulator. Mathematically, this will lead to a singularity in the solution when we solve the poisson equation. Is there a reason why I am not seeing that in the solution generated by omenwire?
