Spin–orbit coupling (SOC) in materials plays a crucial role in interconversion between spin and charge currents. In reduced dimensions, SOC effects are enhanced and have been the focus of intensive experimental and theoretical research, both for their novel spin-dependent phenomena and for their potential exploitation in new spintronics devices. Thanks to the discovery of a family of two-dimensional materials, extensive research has been conducted to explore potential material systems to achieve high spin–charge interconversion rates as well as to allow detection and accurate measurement. This article reviews the prospect of topological insulators as a reliable material system for efficient spin–charge interconversion and recent experimental advances in detecting the charge-to-spin and spin-to-charge conversions on topological insulator surfaces via spin-torque ferromagnetic resonance and spin-pumping techniques, respectively.
