Change Log

Changes in 0.9:

• added dielectric and dielectric_high_frequency parameters
• added meff_e_L_DOS and meff_e_X_DOS parameters
• improved error messages
• fixed MethodParameter.get_references endless loop
• fixed nonparabolicity parameter (temperature dependence was wrong)
• fixed luttinger32 parameter
• fixed lattice matching of type 3 quaternatries

Changes in 0.8:

• Near complete rewrite of internals
• Parameters now have units, aliases, descriptions and references
• Strained alloy interface is much cleaner (see examples/Strained_Ternaries)
• Ternaries of ternaries are now possible (see examples/Ternaries_of_Ternaries)
• Alloy interpolation now follows the recommendations from Vurgaftman, et al. (2001).
• Added and renamed several parameters and methods
• Fixed Ternaries requiring lattice matching temperature

Changes in 0.7:

• Added several functions for calculating the effects of biaxial strain
• Added a strained binaries band offsets vs lattice constant example
• Added several advanced examples
• Fixed the strained binaries bandgap vs lattice constant example (the strain effects were reversed)
• Fixed bug with AlGaN, AlInN, and GaInN caused by having extraneous commas

Changes in 0.6:

• Fixed a packaging issue that prevented setup.py from working

Changes in 0.5:

• Lattice matching temperature is no longer required (defaults to 300 K)
• Added the heavy and light hole effective mass parameters
• Added some new example scripts
• Added quaternary bowing
• Adjusted the InAsSb VBO bowing parameter
• Added some literature references as comments
• Fixed examples not loading local openbandparams

Changes in 0.4:

• Added quaternaries
• Added strained binaries example
• Added ‘elements’ property and ‘elementFraction’ method
• Implemented __all__, so that ‘from openbandparams import *‘ works
• Moved examples into the openbandparams package
• Lots of internal changes (refactoring, documentation, etc.)

Changes in 0.3:

• Added ternary lattice matching

Changes in 0.2:

• Improved usability of ternaries
• Changed all methods to require key word arguments
• Added documentation
