| Phase | Structure | Stability at Room Temp. | Photoactivity | Key Characteristics | | :--- | :--- | :--- | :--- | :--- | | | Cubic (Pm3m symmetry) | Metastable | High (Black) | Ideal bandgap for photovoltaics; Top performer for solar cells | | β (Beta) | Tetragonal | Observed at lower temperatures | Moderate (Black) | PbI₆ octahedra tilt into a distorted cubic structure | | γ (Gamma) | Orthorhombic | Stable at very low temperatures (e.g., below ~180K) | Moderate (Black) | Further octahedral tilting from the tetragonal phase | | δ (Delta) | Hexagonal non-perovskite | Thermodynamically stable | None (Yellow) | Favors face-sharing Pb–I octahedral chains leading to poor optoelectronic properties |

Using the CIF, software like VESTA or Mercury calculates the powder X-ray diffraction pattern. Key peaks for α-FAPbI₃:

Once downloaded, you can render the 3D atomic structure using several free scientific software tools:

can exist in different phases, the CIF file needed depends on the phase being studied. FAPbI3FAPbI sub 3 (Cubic/Black Phase) fapbi3 cif file

A CIF for FAPbI3 contains standardized sections. Key CIF data items include:

cations. When downloading a FAPbI3 CIF file, researchers must carefully select the correct structural phase.

If you have a specific CIF file (like one named "fapbi3.cif") and are looking for help with its contents or how to use it, providing more details about the file or what you aim to achieve could help in giving a more precise response. | Phase | Structure | Stability at Room Temp

Researchers use CIF files in software like VESTA or Mercury to generate 3D models to visualize the PbI6PbI sub 6 octahedra tilting and orientation.

A Crystallographic Information File (CIF) is a text file used to represent crystallographic data in a standardized format. CIF files are used to describe the crystal structure of materials, including their atomic coordinates, lattice parameters, and other relevant information. The CIF format was developed by the International Union of Crystallography (IUCr) to facilitate the exchange of crystallographic data between researchers and software packages.

): This is the black, photoactive perovskite phase. It features a cubic structure (space group Pm3m ) at high temperatures. It can change to a tetragonal or orthorhombic structure as it cools down. Delta Phase ( FAPbI3FAPbI sub 3 FAPbI3FAPbI sub 3 (Cubic/Black Phase) A CIF for

A typical CIF file contains the following critical data blocks:

The FAPBI3 CIF file has several applications in materials science and related fields. Some of the key applications include:

CIF files are the starting point for all DFT calculations. Most workflows convert a CIF to a specific input format:
