Direct observation of anisotropic exciton dispersion in the 2D semiconductor CrSBr

Yiwen Song, Peiyi He, Weizhe Zhang +7

The authors use momentum‑resolved electron energy‑loss spectroscopy and first‑principles calculations to measure exciton dispersion in multilayer CrSBr, revealing a strong in‑plane…
