Structure of ACBI3

ACBI3 belongs to the family of halide perovskites, which are known for their distinctive ABX3 crystal structure. In this structure, 'A' represents a monovalent cation, 'B' is a divalent metal cation, and 'X' is a halide anion. The specific composition of ACBI3 includes cesium (Cs) as the 'A' cation, bismuth (Bi) as the 'B' cation, and iodine (I) as the 'X' anion.

The crystal structure of ACBI3 is typically cubic or tetragonal, depending on the temperature and specific synthesis conditions. This structure is crucial for its electronic properties, as it influences the material's bandgap and charge transport characteristics.
