WebThus, the optical property of a material is largely dependent on the plasmons in it. Due to the spin-momentum locking, the plasmons that are formed by TI surface carriers (known as the Dirac plasmons), are correlated electron density waves as well as spin density waves. These spin density waves are essentially spin plasmons. WebDec 1, 2024 · The corresponding layer locking of the in-plane-canted spin is related to the separation in energy of the highest AFM band from the rest of the valence bands.
