a Representative TEM image of the Bi2Te3 precipitate in the Bi-doped Te matrix. Atomic-resolved HAADF-STEM images for b Te, c Bi2Te3, and d the interface domain, respectively. In e1 and e2, fast Fourier transform (FFT) patterns are calculated from the region indicated by the red and yellow marks in d, respectively.
