open source semiconductor band parameters
The main goal of this project is to provide easy access to semiconductor band parameters for calculations and simulations. Basic functionality requires only the standard python distribution.
Example scripts are provided for basic usage and for generating common plots such as bandgap vs. lattice constant and bandgap vs. alloy composition.
