The humble is the unsung hero of computational perovskite research. Whether you are calculating the formation energy, simulating charge carrier mobility, or training a neural network force field, the accuracy of your results begins with a single, properly sourced crystallographic file.

). Some refinements at room temperature suggest a trigonal ( P3m1cap P 3 m 1 ) symmetry due to slight tilts. : Approximately Significance : It features corner-sharing PbI6cap P b cap I sub 6

You need a CIF with all symmetry information preserved. The training dataset should include CIFs from multiple deformed states. Ensure your source CIF has accurate H positions—many XRD-derived CIFs place H atoms poorly. Re-optimize H positions using DFT (e.g., VASP + IBRION=2 with H frozen in a few iterations). fapbi3 cif file

– A minor occupational disorder (~0.12) was modelled for the terminal methyl group (C12). The disorder was refined with a similarity restraint on the C–C distances (SADI). No residual electron density indicative of unmodelled disorder remains.

The material is highly polymorphic, meaning it exists in several crystal phases depending on temperature and pressure. 1. The Alpha Phase (

By following this guide, you ensure that your simulations of FAPbI₃ are reproducible, physically meaningful, and aligned with the experimental community. Now—go download the correct CIF and run that calculation. Some refinements at room temperature suggest a trigonal

Re-download the CIF from the Materials Project (DFT-optimized for 0K) or use the experimental 300K CIF from CSD. Re-run the calculation. The corrected bandgap allows the researcher to correctly model the J-V curve of the perovskite solar cell.
