TEM, HRTEM, and elemental mapping images of the rod-like nanostructures. (a) Low-magnification TEM image of several In-Sn-O nanostructures. The EDS spectra taken from the stem and particle were also displayed. (b) HRTEM images taken from the different regions of the individual nanostructure and the selected area electron diffraction patterns from the stem and particle. (c) The In and Sn elemental mapping images taken from the red square region of the nanostructure. The intense peak at approximately 8 keV originated from the copper grid.
