Does MatCraft include experimental data?

MatCraft primarily contains computationally predicted (DFT) properties, not experimental measurements. This is because:

1. Computational data is systematic and covers a much larger chemical space
2. DFT calculations provide a consistent set of properties for every material
3. Experimental data is scattered across literature and difficult to aggregate uniformly

However, some experimental context is available:

• ICSD (Inorganic Crystal Structure Database) structures are used as starting points for many DFT calculations
• The Materials Project validates key materials against experimental data
• JARVIS includes comparison with available experimental band gaps

For experimental properties, we recommend complementary databases like the NIST Materials Data Repository, Springer Materials, or Citrine Informatics.
