The "yellow phase." It consists of face-sharing octahedra, which traps charges and prevents efficient solar energy conversion.
Provides computed CIF files along with predicted electronic properties. fapbi3 cif file
-phase (yellow, hexagonal). Understanding this transition starts with the crystal structure. What is a CIF File? The "yellow phase
A is the standard format for exchanging crystallographic data. It contains everything needed to reconstruct the 3D lattice of a material, including: Unit cell dimensions (a, b, c) and angles ( Space group symmetry (e.g., Pm3m for cubic FAPbI₃). It contains everything needed to reconstruct the 3D
For researchers, the CIF file is the "blueprint" used in software like VESTA, Diamond, or Mercury to visualize the crystal and perform DFT (Density Functional Theory) simulations. Key Phases of FAPbI₃ and Their Crystallographic Data
A massive open-access collection of crystal structures.
