Figure 2. Characterization of ZnO nanowires synthesized by decomposing zinc acetate at ∼300 °C in trioctylamine. (A) SEM micrograph of wires grown
for 1 h. (B) TEM image of several nanostructures showing the parallel nanowires and nanorods. The inset is a diffraction pattern taken from a singlecrystalline
ensemble; both the base and wires grow along the [0001] direction. (C) High-resolution TEM image of a single nanowire (16 nm in diameter).
