Composition analysis of a Bi2Te3 nanowire. (a) A HAADF image of the Bi2Te3 nanowire. (b) EDS line scan profiles showing the distributions of Bi (cyan, 39%) and Te (red, 61%) through the nanowire. (c,d) Elemental mapping images show the uniform distributions of Bi (cyan) and Te (red) along the nanowire.
