Ultrafast long-range spin-funneling in solution-processed Ruddlesden–Popper halide perovskites

Abstract

Spin-information transport or transfer is essential for spintronics applications and often relies on high purity and quality materials. Here, the authors report on the defect-tolerant solution-processed Ruddlesden–Popper halide perovskites, where a spin propagation length of 600 nm was achieved via spin funneling.
