An Open Source 1-dimensional self-consistent Schrödinger-Poisson solver for Linux. #Schrodinger-Poisson solver #Semiconductor heterostructures #Self-consistent solver #Schrodinger #Poisson #Solver
Aestimo is an open source and completely free command-line software implemented in Python and created from the ground up to act as an one-dimensional (1D) self-consistent Schrödinger-Poisson solver that can be used for semiconductor heterostructures.
The software was successfully used as a usable co-tool in a scientific and/or educational work environment. It supports a wide range of alloys and materials, among which we can mentiion GaAs, InAs, AlAs, InP, GaP, AlP, AlGaAs, InGaP, AlInP, and InGaAs.
Key features include band structure for gamma electrons, as well as for heavy, light and split-off holes, 3x3 k.p method for holes and effective-mass method for electrons, carrier concentrations for heavy, light and split-off holes, as well as for gamma electrons.
The software comes with an electric field distribution, electron wavefunctions, non-parabolicity, external electric field, strain for valence band calculations, and many other attractive features for your to discover.
The software is a bit complicated to use, as it must be used from a console environment, such as a terminal emulator software. You must first download the latest release, save the archive on a location of your choice (preferably your Home directory), and uncompress it.
Open a Terminal app, go to the location where you’ve extracted the archive file (e.g. cd /home/softpedia/aestimo_1_0), and run the ‘python aestimo.py --help’ command to view the program’s usage message.
Basically, there’s a single command-line option for the Aestimo software, -i INPUTFILE (usage: aestimo.py --inputfile=INPUTFILE), allowing you to chose the input file to override the default one in config.py. Several samples are provided in the source package, so you can get a taste of what Aestimo can do.
What's new in Aestimo 1.0:
- This version includes many bugfixes, new organization of the structure, wurtzite material using, lots of change in intersubband optical transitions module. Dielectric constants are now handled more accurately. Many tutorials are added in the form of an ipython notebooks. Code is heavily modified and stabilized with more than 60 commits. This version is the most feature rich and stable version so ever. For more please visit release notes. Also another aestimo version, which is called “elementary” is released. This version is easy to understand in terms of coding, and therefore it can be used in undergraduate/graduate courses and forking new solvers. There will be no any other release for the “elementary” version.
