3d MOSFET

Here is Devsim’s first 3d simulation of a MOS transistor.  The coloring is the potential at zero bias.

gmsh for 2d mosfet

Here is a 2d mosfet meshed with Gmsh and loaded into Devsim. Note that this is the same structure and doping which was originally shown here in my first post.

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.

First 3d result

3d diode

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.
