Dataset Name

Halide Perovskite Ion Migration MLFF negative iodide interstitial

Description

VASP machine-learning-force-field (ML_AB) training set for the CsPbI3 halide perovskite, covering migration of a negatively charged iodide interstitial. This is one of seven sister datasets from the same publication, each providing a VASP ML_AB training set for a slightly different characteristic of the CsPbI3 perovskite (the cubic-tetragonal phase transition and the migration of iodide vacancies and interstitials in neutral, positively charged, and negatively charged states), all generated to train machine-learned force fields for ion migration. Each configuration carries the total energy, atomic forces, and stress from VASP single-point reference calculations using the PBE functional with Grimme D3 dispersion and Becke-Johnson damping (PBE-D3-BJ), on 2x2x2 cubic supercells (~40 atoms). (Plane-wave cutoff and k-point details are reported only in the paper's Supporting Information.)

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).
