| 摘要 | Recent theory and experiment have shown that gray arsenic has a Shockley surface state with a topological origin, and is spin polarized by the Rashba spin-orbital coupling. However, there has been no microscopic study of the scattering properties of this surface state, which could reveal its spin structures and quasiparticle dynamics. Here, with scanning tunneling microscopy/spectroscopy, and first-principles calculations, we show that the surface band has a significant out-of-plane spin component at the higher-energy part, unlike what a basic Rashba effect would produce. We also show that the spin-coherence length of gray arsenic at liquid-helium temperature to be longer than 70 nm, which is larger than its spin procession length and indicates the potential spintronic applications based on the Rashba state of gray arsenic. © 2024 American Physical Society. |
