Welcome to the Open Quantum Materials Database

The OQMD is a database DFT calculated thermodynamic and structural properties. We are providing this online interface for convenient, small scale access; however for more powerful utilization we recommend downloading the entire database and the API for interfacing with it, detailed in the link below.

You can...

Tweet @TheOQMD to ask what is stable at a composition, or to get a simple phase diagram!

The OQMD was created in Chris Wolverton's group at Northwestern University.
