Sept. 8, 2020: Supplemental Database Release V2020.09.08

This release addresses issues identified with the formation energies of a minority of materials. A second supplemental release is planned. More info in our release logs.

Aug. 21, 2020: Database V2020.08.21 Released

In this release we have added thousands of new band structure and density of states calculations, improving our overall material coverage and data quality. Additionally, we have overhauled the plotting for these quantities on the material details page. This is a first step in improving the electronic structure data within the Materials Project as part of our new tool set for band structure calculations. We are also working through an on-going issue affecting the energies of a small number of materials. More info in our release logs.

July 2, 2020: Do you have data to share with our community?

If you feel comfortable with Python, use our dedicated MPContribs platform to contribute your data to MP. We automatically expose it to MP users on our materials details pages. Get started with this docs page and feel free to join our Slack group for questions. Stay tuned for more features and documentation :)

June 30, 2020: Database V2020.06 Released

We've added several thousand materials including many magnetic ground states, improved the accuracy of our energetics, and fixed several bugs. This database release is part of on-going efforts in 2020 to improve database reliability and quality, following the introduction of our deprecation process last year. More info.
