Exciton Transport in Perovskite Materials
This review discusses the spatiotemporal dynamics of excitons in halide perovskite materials, with a particular emphasis on low?dimensional perovskites and the effects of nanoscale morphology on excitonic behavior. Novel phenomena unique to halide perovskites are emphasized while introducing the basic theory needed to understand the importance of those observations.Halide perovskites have emerged as promising materials for a wide variety of optoelectronic applications, including solar cells, light?emitting devices, photodetectors, and quantum information applications. In addition to their desirable optical and electronic properties, halide perovskites provide tremendous synthetic flexibility through variation of not only their chemical composition but also their structure and morphology. At the heart of their use in optoelectronic technologies is the interaction of light with electronic excitations in the form of excitons. This review discusses the properties and behavior of excitons in halide perovskite materials, with a particular emphasis on low?dimensional perovskites and the effects of nanoscale morphology on excitonic behavior. The basic theory of excitonic energy migration in semiconductor nanomaterials is introduced, and novel observations in halide perovskite nanomaterials that have evolved our current understanding are explored. Finally, many important questions that remain unanswered are presented and exciting emerging directions in low?dimensional perovskite exciton physics are discussed.
