Extreme Polarization of the Optical Gap and High-Energy Exciton Landscape in CrSBr

Sayantan Patra, Sourabh Jain, Bhumika Chauhan +8

We reveal a strongly anisotropic excitonic landscape in monolayer and bulk-like CrSBr using optical absorption spectroscopy and $GW$-Bethe-Salpeter equation $\text{ab initio}$ ca…
