Extended Data Fig. 5: Structural analyses of RE+-intercalated superlattices.
From: A cation-exchange approach to tunable magnetic intercalation superlattices
Cross-sectional HAADF-STEM images and corresponding structural models of Eu1/3MoS2 superlattice along (a,b) “zigzag” direction and (c,d) “armchair” direction. Cross-sectional HAADF-STEM images of Eu1/3MoS2 superlattice revealed that the Eu cations are centered within the vdW gap, occupying the octahedral interstitial sites, which is consistent with the larger ionic radius of Eu3+ (95 pm) compared to Co2+ (75 pm) and Li+ (76 pm). Scale bars, 0.5 nm. e,f, Cross-sectional HADDF-STEM images of GdxNbSe2 superlattice (e) and EuxWTe2 superlattice (f). Scale bars, 0.5 nm. Blue, Mo; yellow, S; red, Eu.
