effmass vs ParticlePhaseSpace
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.

ParticlePhaseSpace offers a broad, extensible workflow for particle phase-space data at no listed cost. Users should account for format-specific omissions, IAEA setup requirements, and the caution attached to KDE resampling.

effmass: what it does well
- Calculates several effective-mass types
- Assesses non-parabolicity with Kane parameters
- Locates band extrema
- Plots dispersion approximations
- Available free on Linux, macOS, and Windows
What to know first
- Quasi-Fermi estimates require VASP DOSCAR
