# Dataset Name |
|
|
Ta PINN 2021 |
|
|
### Description |
|
|
A dataset consisting of the energies of supercells containing from 1 to 250 atoms. The supercells represent energy-volume relations for 8 crystal structures of Ta, 5 uniform deformation paths between pairs of structures, vacancies, interstitials, surfaces with low-index orientations, 4 symmetrical tilt grain boundaries, γ-surfaces on the (110) and (211) fault planes, a [111] screw dislocation, liquid Ta, and several isolated clusters containing from 2 to 51 atoms. Some of the supercells contain static atomic configurations. However, most are snapshots of ab initio MD simulations at different densities, and temperatures ranging from 293 K to 3300 K. The BCC structure was sampled in the greatest detail, including a wide range of isotropic and uniaxial deformations. |

# Usage |
|
|
- `ds.parquet` : Aggregated dataset information. |
|
|
- `co/` directory: Configuration rows each include a structure, calculated properties, and metadata. |
|
|
- `cs/` directory : Configuration sets are subsets of configurations grouped by some common characteristic. If `cs/` does not exist, no configurations sets have been defined for this dataset. |
|
|
- `cs_co_map/` directory : The mapping of configurations to configuration sets (if defined). |
