Here is DEVSIM’s first 3d simulation of a MOS transistor. The coloring is the potential at zero bias.
It just looks a lot better having used a nicer meshing tool than the one built into the software.
As before, the red areas are the electron concentration.
Turns out Gmsh was an excellent choice for a mesher. It is a very usable tool for creating structures Almost reminds me of mdraw.
The result is a 3d (quasi-1d) diode structure. The spot in the middle is the magnitude of the electric field. Visualization is done in Paraview.
