Innovation of Materials, Devices, and Functionalized Interfaces in Organic Spintronics

Abstract

AbstractOrganic spintronics has been attracting the interest of the scientific community because of its potential to complement the electronics industry by combining the spin and charge degrees of freedom. Synthesized organic materials with light elements have been widely applied in organic spintronics due to their intrinsic weak spin‐orbit coupling and hyperfine interaction. Meanwhile, the prototypic devices in inorganic spintronics have been creatively utilized to fabricate analogous organic devices. The interfaces between organic materials and ferromagnetic electrodes in spintronic devices are diverse and can lead to many novel phenomena that influence the device performance. In this review, the novel organic materials, innovative devices, and functionalized interfaces in organic spintronics are comprehensively introduced. First, the fundamental concepts and parameters of organic spin devices are clarified. Subsequently, the organic materials applied in organic spintronics are classified, which include small molecules, polymers, and organic–inorganic hybrid perovskites. Moreover, several types of spin‐related devices in this field are introduced and discussed. Thereafter, the functionalized interfaces of the spin‐related devices are categorized and elaborated upon. Finally, a brief summary and future prospects are presented, which highlight the developments necessary in organic spintronics in the near future.
