Procedures and Properties for a Direct Nano-Micro Integration of Metal and Semiconductor Nanowires on Si Chips

Figure 1

(a)–(d) show nanostructures grown by conventional VLS approach, (a) transmission electron microscope (TEM) image of ZnO nanorods with Au NPs on their heads (inside dotted circles); (b), (c), and (d) scanning electron microscopy (SEM) images ZnO nanoSails at different magnifications. The presence of Au NP on the top of nanoSail can be clearly seen in 1D (inside dotted circles). (e) and (f) show the structures grown by modified VLS approach [24] without any catalytic NPs: (e) ZnO nanomast structures, (f) ZnO nanorods, and (g) tin oxide nanowires.
