open source semiconductor band parameters

Project description

This is the first public release of openbandparams.

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, bandgap vs. alloy composition. Documentation
is available at

Included parameters:
- lattice constant
- thermal expansion coefficient
- bandgap energies (direct and indirect)
- Varshni parameters
- split-off energies
- effective masses
- Luttinger parameters
- Kane parameters (Ep and F)
- Valance band offsets
- band deformation potentials
- elastic constant
- alloy bowing parameters

Included materials:
- III-V's
- Zinc Blendes
- Binaries
- AlN, GaN, InN,
AlP, GaP, InP,
AlAs, GaAs, InAs,
AlSb, GaSb, InSb
