a Typical TEM image, revealing the segmented periodic heteronanostructure. b HAADF and EDS mapping, showing the homogeneous distribution of Te (orange) and heterogeneous distribution of Ag (blue). All scale bars are 50 nm. c HRTEM image, showing the specific interface between Te and Ag2Te. d A schematic atomic model, specifying an atomically sharp interface in heteronanostructures. The hexagonal Te (001) plane connects with the monoclinic Ag2Te (−204) plane. e XRD pattern, showing the coexist of Te and Ag2Te. f, XPS spectra of Te 3d orbital of the heteronanostructures. g Time-resolved TEM images. t = 10 s, 30 s and 3 min for Stage 1, 2, and 3, respectively. t is the reaction time between Te and Ag+. h, HRTEM image of the island on the NW. Inset: TEM image of the nanostructure formed at the beginning. i The distribution of Ag2Te island formed on the Te NW, obtained by line analysis of EDS. Inset: HAADF image of island formed on the NW. Source data are provided as a Source Data file.
