Phase Diagram
Let's you browse entries in our database, view the crystal structure and its associated properties. Lets you generate binary and ternary phase diagram using various correction scheme.

Disclaimer: the MP2020 correction scheme has not yet been uniformed across datasets, when using this correction scheme please be cautious about interpreting data. We will fix this in upcoming release!
## Stay tuned for future updates We plan to release very soon: - Band gap information on all materials, including direct and indirect band gaps. - Unification of energy corrections (currently a beta version of this is available for the purpose of the phase diagram application, but please see the disclaimer above). - Bader charges for all Materials Project materials where possible and the addition of charge data from Alexandria and OQMD - R2SCAN data from Materials Project In the longer run we plan to release additional datasets including trajectories and surface, adsorbates, and molecules. And more! Stay tuned. ## **Support** If you run into any issues regarding feel free to post your questions or comments on any of the following platforms: - [**HF Discussions**](https://huggingface.co/datasets/LeMaterial/LeMat-Bulk/discussions) - [**Github Issues**](https://github.com/LeMaterial/lematerial/issues) ## License This database is licensed by [Creative Commons Attribution 4.0 License](https://creativecommons.org/licenses/by/4.0/).
