Spintronics of Hybrid Organic–Inorganic Perovskites: Miraculous Basis of Integrated Optoelectronic Devices

Hybrid organic–inorganic perovskite (HOP) spintronics aims to make full use of the properties of electron spin. HOP spintronics has recently emerged as a promising field of research because it provides a new precisely manipulable degree of freedom. The flourishing development activity in this field has benefited from the unique intrinsic spin‐related optoelectronic properties of HOPs, which include triplet formation, a large Stark effect, the magneto‐optical effect, polarized light‐related effects, and complex light emission characteristics, which offer the possibility of providing a new way to control the performance of integrated optoelectronic devices through spin interactions between photons and electrons. Along with the continuous improvements in the theoretical research into HOP spintronics, large numbers of novel optoelectronic devices have been proposed and demonstrated experimentally and have shown great potential for fabrication of next‐generation, high‐performance integrated optoelectronic chips. This review provides an overview of the fundamental principles, novel spin‐generated physical effects, and diverse structures of HOP spintronics systems, along with the applications of HOP spintronics in optoelectronic devices, while also undertaking a general review of the remaining challenges and proposing possible development directions that require further study for the application of HOP spintronics to integrated optoelectronic devices. Hybrid organic–inorganic perovskite (HOP) spintronics has developed as an emerging research area and shown tremendous potential for applications in integrated optoelectronic devices. This review summarizes the basic realization mechanisms, novel spin‐generated physical effects, diversified structure of HOP spintronics systems, applications of HOP spintronics in integrated optoelectronic devices, and the research status as well as challenges in the field.
