Figure 4

Typical TEM images of nanostructures obtained at 950°C at the upper part of the sample. (a) TEM image of stringlike nanowire assemblies. (b) TEM image of stringlike nanowire assemblies with the catalyst at the tip. (c,d,e) TEM images of a bamboo-like nanostructure with large bowl-like, cuplike, and vase-like joints, respectively. (f) HRTEM image of the gap between the two joints.
