a Three-dimensional representation of the real-space crystal structure of CrSBr, created with the VESTA software package69. The pink rectangular prism represents the unit cell. b The corresponding Brillouin zone of CrSBr with high symmetry points labeled. c Self-consistent GW calculations of the electronic band structure of monolayer CrSBr along high symmetry directions in the ΓXSY plane. d Reflection contrast and photoluminescence spectra of bulk CrSBr at 40K. Features in the two spectra are in excellent agreement, revealing an optical gap at Γ of 1.362 eV.
