A results database of first-principle calculation for material science. This database provides numerical data of crystal structures, band structures, thermodynamic quantities, phase diagrams, magnetic moments, and so on. This site is maintained by a research group of Duke University, and in particular, has extensive data of Heusler alloys. In addition to a user interface based on web browsers, an http-based API is also provided to enable user-defined material screening. This database can be used without charge after registration.
A fee-charging structure database of organic materials crystal structures. Three-dimensional structure data of small molecules and metal-organic crystals determined by the X-ray diffraction measurement can be downloaded. The data are compiled and distributed by the Cambridge Crystallographic Data Centre (CCDC).
A database of structures and properties for various materials including polymers and inorganic substances. This database is maintained by National Institute of Materials Science (NIMS), and provides crystal structures, various physical properties, and phase diagrams for material science via a user interface based on web browsers. This database also provides calculation results of phase diagrams and electronic structures. This database can be used without charge after registration.
A commercial database of inorganic crystal structures. This database is run by FIZ Karlsruhe. 181,000 crystal structure data are registered as of March 2016. 6,000 crystal structure data are added per year on average, and data are updated twice per year based on data in published scientific journals.
A structure database for proteins and nuclear acids. Three-dimensional structure data of proteins and nuclear acids (atomic coordinates determined experimentally by X-ray crystal analysis, NMR, etc.) can be downloaded. The data reposited in PDB are in the public domain, and can be accessed by everyone freely.
An open-access database of crystal structures. This database includes structural data of organic, inorganic, metal-organic compounds and minerals. At the end of 2017, this database contains about 400,000 entries. Three-dimensional structures of crystals can be viewed by GUI on the web.
An application for calculating thermal transport properties based on the phonon Boltzman equation. This application has its own database for phonon properties of materials, and can utilize it for evaluating heat conductivity and specific heat of crystals, alloys, and heterostructures combining them. Phonon-energy resolved contribution to heat conductivity and specific heat can also be calculated. This application also supports calculation of time-dependent response and steady state analysis.
Starrydata is an open database of experimental data from figures in published papers. Thermoelectric properties such as Seebeck coefficient, electrical resistivity and thermal conductivity are presented mainly on thermoelectric materials.
An open source library for implementing tensor networks. It is developed based on TensorFlow and is designed to be easily used by experts in the field of machine learning as well as in the field of physics. In addition to TensorFlow, it includes wrappers for JAX, PyTorch, and Numpy.
A database for thermodynamic properties and crystal structures calculated based on the density functional theory by a research group in Northwestern University. OQMD provides over one million data generated by using not only experimental crystal structures provided by ICSD but also those obtained by calculations. Users can search data in OQMD by using Python API.
