I was looking to do some simulation for a tunneling diode I have been designing. It is essentially a silicon dioxide insulator between two polysilicon mediums (of a particular geometry as shown in the picture below). I have added the materials from the available material options (both from semiconductor materials package and other packages like MEMS). I am looking to calculate the tunneling current through the device from the triangular side to the island side. However, when I do the 2D simulation the results does not show a IV curve as it does in many of the online tutorials, which I am not sure why. Also, I had made a 3D model, also shown, which is more specific with regards to boundary conditions and more explicitly describing the actual device. This is what I am more interested in, but also worked with 2D since it is a bit easier.
Help in figuring out how to check for a tunneling current using the 3D model would be greatly appreciated, as I am relatively new to the software. Further information regarding the design can be seen in the .mph of the 3D version provided.
Note: in the image provided the oxide fill (or oxide tunneling medium) is exagerated for display purposes. It is the correct size in the .mph file.
