Fig. 5. The atomic registry-dependent band structure of G/four-layer CrI₃ under AFM and FM interlayer coupling.

a–d The band structure and norm-squared wavefunctions of bands in G/four-layer CrI₃ with FM and AFM interlayer order in the hump and valley geometries. The top panel shows the band structure of G/four-layer CrI₃. We indicate four states using red dashed lines shown in each of the four cases. The middle panel shows contour plots of the norm-squared wavefunctions of indicated states averaged over the y-direction of the heterostructure. The bottom panel shows the norm-squared wavefunctions of indicated states averaged over the entire plane.
