effmass vs View-Physics
Both stand on physics simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacWindows
effmass provides focused semiconductor bandstructure calculations through both command line and Python interfaces. Its broader non-parabolic analysis and quasi-Fermi estimate are available through the package’s documented workflows and dependencies.
