We are pleased to share that our invited Mini Review, “Spin Lifetime in Hybrid Organic-Inorganic Perovskites: Mechanisms, Measurements, and Prospects for Spintronic Applications,” has been published in The Journal of Physical Chemistry Letters.
Hybrid organic-inorganic perovskites (HOIPs) have attracted growing interest in the spintronics community due to their strong spin–optoelectronic coupling, structural tunability, and the ability to engineer spin-orbit interactions. Among the key physical parameters determining device performance, spin lifetime plays a central role in maintaining spin coherence and enabling reliable spin transport.
In this Mini Review, we provide a comprehensive overview of spin lifetimes in HOIPs, as reported by various optical and electrical techniques, with measured values ranging from 0.2 ps to 2 ns. We summarize four main spin decoherence mechanisms—Elliott–Yafet, D’yakonov–Perel, Bir–Aronov–Pikus, and polaron-related—and analyze how experimental methods such as time-resolved Faraday/Kerr rotation, circularly polarized transient absorption, and Hanle effect spectroscopy reveal different aspects of spin dynamics.
The review also compares HOIPs with other spintronic material systems, including nitrogen-vacancy centers in diamond and organic semiconductors, highlighting the relative advantages and persistent challenges of HOIPs in achieving long spin coherence at room temperature. The article concludes with an outlook on promising research directions, including materials design, defect passivation, and developing next-generation spin-sensitive measurement techniques.
This work received contributions from Profs. Qiong Chen, Jingying Wang and Young-Hoon Kim, reflecting collaboration between researchers at Hunan Normal University, Sun Yat-Sen University, and Hanyang University (Korea).
Congratulations to the team!
