HTEM DB

The High Throughput Experimental Materials Database (HTEM DB) is an open-access repository dedicated to experimental data for inorganic thin-film materials. The database aims to enable the discovery of new materials with useful properties by providing large amounts of high-quality experimental data to the public. It contains over 140,000 sample entries collected from combinatorial experiments at the National Renewable Energy Laboratory (NREL), covering synthesis conditions, chemical composition, crystal structure, and physical properties. It is designed to complement computational databases (like the Materials Project) by providing experimental validation and datasets for machine learning.
