a Cross-sectional HAADF-ABF images of a Bi2Te3 nanoplatelet. Brown, blue, and magenta dots indicate the Bi, Te(1) and Te(2) columns in the quintuplets. b The intensity profile from the cross section (yellow line) in the HAADF image. c 125Te static frequency sweep NMR (yellow circles) and the isotropic projection of the 2D 125Te aMAT NMR at 14 kHz MAS (solid line) of bulk Bi2Te3. d 125Te static frequency sweep NMR (gray circles) and the isotropic projection of the 2D 125Te aMAT at 30 kHz MAS of a Bi2Te3 nanoplatelets sample.
