- ABX3Cubic perovskites are a class of semiconductors represented by the chemical formula ABX31. They are metal-halide perovskites, where A is a cation, B is a divalent metal ion, and X is a halogen anion1. Perovskite crystals may appear to have the cubic crystal form, but are often pseudocubic and actually crystallize in the orthorhombic system2.Learn more:✕This summary was generated using AI based on multiple online sources.
