| Planar Defects Ontology (PLDO) |
| ======================================================================================================================== |
|
|
| Overview |
| -------- |
| PLDO is an ontology designed to describe planar defects in crystalline materials, |
| such as grain boundaries and stacking faults, with a focus on their atomic-scale structure and properties. |
