XRD spectra and high-resolution TEM image. (a) XRD spectra of ITO NWs. (b) A high-resolution TEM image of ITO nanowire. The inset shows a corresponding selective area diffraction pattern, revealing that [100] is a preferred growth direction. (c) Chemical bonding information of In, Sn, and O for the ITO NWs extracted from the XPS spectra.
