Hence the crystallographic relationship comes out to be [110]In2O3, [1120]ZnO for the 6-fold symmetry. When In2O3 is along the [110] direction, the core nanowire is enclosed by r[112], r[112], and r[110] facets. The angle between each of these adjacent facets is very close to 60q, so a quasi 6-fold symmetry is often observed when an In2O3 nanowire grows along the [110] direction. 16(h)), where hexagon end planes are clearly observable at the end of major cores and on secondary ZnO. A detailed conclusion on the orientation relationship of 6-fold symmetry in contrast to 4-fold symmetry is given later.

3. ZnO nanorods can be grown on an In2O3 nanowire core with various symmetries and orientations by vapor transport and condensation. , 1,975 qC and 1,931 qC respectively). We therefore mixed in graphite powder as a reducing agent, which brings down the reaction temperature to below 1,000 qC. A mixture of ZnO, In2O3, and graphite powders can be used as a coevaporation source to be placed at the sealed end of a single-ended sealed quartz tube (shown in Fig. 1). The nanostructures can grow on many different collectors, including graphite foil, single crystal silicon, and LaAlO 3.

15. Large quantity hierarchical ZnO nanostructures are shown in Fig. 15(a). Under medium magnification, Fig. 15(b) clearly shows all the major 6-, 4-, and 2-fold structural symmetries. The length of the major In2O 3 core is usually on the order of tens of microns, and the diameter is between 50 and 500 nm. 2 Pm in length and possess a diameter between 20 and 200 nm. They are oriented either normal to or at an angle to the core surface. 15 SEM images of the ZnO nanostructures synthesized by vapor transport and condensation technique.
