List of Properties¶
In this section of the documentation, we review in detail the physical relevance and description of each property available for computation.
Illustrations of the JSON schemas and associated examples for each property discussed in the present section are contained in this page, and referenced at the end of each property's dedicated description.
At the top of each property's page, we include colored badges referring to the property classification, distinguishing between scalar and non-scalar types and between the different types of Materials Properties.
Below we provide a list of Materials properties that can be extracted on our platform. The reader can click each entry to be redirected to the relevant documentation explanation.
