Aestimo 1D
Aestimo simulates one-dimensional semiconductor heterostructures using Schrödinger–Poisson and drift–diffusion methods. It provides a command-line interface, a Python interface and a desktop GUI with device presets.
Install Aestimo
Install the published package in an activated Python environment:
python -m pip install aestimo
The desktop GUI described here is part of the upcoming 4.0.0 release. Until that release is published on PyPI, use the source installation to try it. See Installation for environment setup and desktop requirements.
Getting started
Follow Your first calculation for a quantum-well calculation with a short physical interpretation. Use Desktop GUI to build and run a desktop project, or Command-line quick start for Python inputs and command-line calculations. Tutorials includes the notebook tutorials.
About the project
Started in 2012, Aestimo is an open-source educational and research tool. Its layer-based model resolves band profiles, confined carrier states and electrostatic properties along a semiconductor structure’s growth direction.
