The making of a reconfigurable semiconductor with a soft ionic lattice

Synthetic understanding is crucial for designing halide perovskites with controlled properties and for paving ways to create a new fam-ily of structures. With expanding synthetic approaches, it is espe-cially necessary to elucidate the formation of halide perovskites and how that influences their associated properties to inform a uni-fying design principle. In this perspective, we summarize key mile-stones in the synthesis community of inorganic halide perovskite nanostructures and highlight how the reaction kinetics and thermo-dynamics of halide perovskites distinguish them from traditional inorganic semiconductors. We then present a retrospective view that conceptually unites physical chemistry theories with advanced synthesis and address lingering questions in the field along with possible solutions. This perspective aims to articulate the relation between structural properties, synthetic tunability, and the environ-mental stability of halide perovskites and to provide an outlook for new generations of halide perovskite nanostructures for efficient and stable devices.
