Is there a package which can solve drift-diffusion and Poisson’s equations for isotype heterojunctions? I think 1D would be enough.

I am asking as I would be interested in understanding thermal emission or tunneling transport at such interfaces.

I have not seen any mention of TCAD myself. All I can give you are a few leads.

If you are thinking of assembling your own solution:

- [https://github.com/JuliaFEM](https://github.com/JuliaFEM)
- [https://github.com/JuliaGeometry:](https://github.com/JuliaGeometry:) Looks like meshing algorithms
- [https://github.com/JuliaWaveScattering:](https://github.com/JuliaWaveScattering:) Don’t think they do charge flow, though.

You can also take a look at my EDA aggregator page:

- [Free EDA | ma-laforge](https://ma-laforge.github.io/extresouces/freeeda)

I have a section on TCAD:

- [Technology CAD (Wikipedia) ↪](https://en.wikipedia.org/wiki/Technology_CAD)
- [TCAD Central ↪](https://tcadcentral.com/Software.html): Aggregator.
- [Charon ↪](https://charon.sandia.gov/): Sandia National Laboratories.

There is also PISCES (Stanford), but I don’t know where to find the code:

- [Stanford University - TCAD Software PISCES-2ET](http://www-tcad.stanford.edu/tcad/programs/pisces2et.html)

Thank you for this nice collection of links. I’ll take a look at them.

This project may be applicable, if you have not discovered it already:

[https://github.com/j-fu/VoronoiFVM.jl](https://github.com/j-fu/VoronoiFVM.jl)

The developer of the project has a lot of TCAD experience and has published several papers on drift diffusion formulations.
