Fig. 5: Mechanism of the anomalous exciton blueshift.

a The charge density differences for CrSBr/FGT heterostructure. The pink and green areas depict charge accumulation and depletion, respectively. b The spin polarization rate difference (\(\Delta P\)) of CrSBr in the heterostructure. The red and blue areas represent positive and negative values of the spin polarization rate, respectively. c Micromagnetic simulation results of the exchange interaction and magnetic anisotropy energies of CrSBr in the pristine and heterostructure (extracted from each CrSBr layer). d Schematic illustration of the exciton recombination process in CrSBr under the enhanced AFM configuration.
