I want a simple phonon dispersion calculation, the lighter the program the better I do not want to install some huge package like QuantumExpresso just for that. Another way would be to find a database with phonon dispersion data for different materials, it's there any?
Harnessing the power of supercomputing and state-of-the-art methods, the Materials Project provides open web-based access to computed information on known and predicted materials as well as powerful analysis tools to inspire and design novel materials.
The Materials Project API allows anyone to have direct access to current, up-to-date information from the Materials Project database in a structured way.
This allows for analysis, development of automated tools, machine learning, downloading personal copies of the Materials Project database and more on a large scale.
The API is offered with the hopes of making Materials Project data more useful to you. We want you to use our data! As such, the API is offered free-of-charge and we support several tools to help you get started.
