Extended Data Fig. 2: STEM image and SAED patterns of the intrinsic H-TaS2.

a, STEM image of the basal plane of intrinsic H-TaS2. Blue and yellow dots represent tantalum and sulfur, respectively. Scale bar, 1 nm. b, SAED patterns of intrinsic H-TaS2. Scale bar, 2 nm−1. The in-plane lattice parameter remains unchanged between H-TaS2 and MBA/TaS2 CMIS, confirming that the H-TaS2 host layers retain the original atomic structure with no notable lattice distortion after the formation of CMIS.
