Molecular behavior of zero-dimensional perovskites.

ABSTRACT: Low-dimensional perovskites offer a rare opportunity to investigate lattice dynamics and charge carrier behavior in bulk quantum-confined solids, in addition to them being the leading materials in optoelectronic applications. In particular, zero-dimensional (0D) inorganic perovskites of the Cs₄PbX₆ (X = Cl, Br, or I) kind have crystal structures with isolated lead halide octahedra [PbX₆]^4- surrounded by Cs⁺ cations, allowing the 0D crystals to exhibit the intrinsic properties of an individual octahedron. Using both experimental and theoretical approaches, we studied the electronic and optical properties of the prototypical 0D perovskite Cs₄PbBr₆. Our results underline that this 0D perovskite behaves akin to a mole
