Image of FIG. 1.
FIG. 1.

(a) A low-magnification SEM image showing the representative morphology of nanowires on the substrate and the TEM image of a single nanowire inserted at the right corner. (b) An EDS spectrum of a single nanowire. The inset is elemental mapping crossing the nanowire.

FIG. 2.

XRD pattern confirming the synthesized nanowires coincident with the crystal structure of : (a) standard diffraction data of given by JCPDS file No. 28-1486 and (b) experimental XRD pattern of the synthesized nanowires.

Image of FIG. 3.
FIG. 3.

High resolution TEM image of individual nanowire showing grain boundary and out-of-phase boundary. The corresponding diffraction pattern is inserted at the right top corner depicting the relative orientation of grains.
