ofhierarchical ZnOnanostructure with widths of 70–-120 nm and average length of around 600 nm. The high-magnification image of the single nanorod on the side-wall displays columniform structure with a conic tip which is quite different from the hexagonal structure in Fig. 1(d), indicating that the ZnO nanorods are not synthesized through the layer-by-layer growth model. It is noticed that

∙ ZnO is an good candidate for fabrication of optoelectronic
andelectronic device.
∙ 1D ZnOnanostructures have many properties.
∙ It is that a simple two-step thermal evaporation process
to synthesize the hierarchical pure ZnOnanostructures of 6-fold structural symmetry without any metal catalyst.
∙ Pure zinc powder(99.99%)
of cross-linked nanonetworked with nanometallic electronic conductivity has been reported in a previous communication. Bard and co-workers have extended this method for the fabrication of self- assembled spherical ultramicroelectrodes by confining the self-assembly process to the tip end of a quartz micropipet.
The present paper focuses on the unusual optical andelectronic properties of multi
For comparative purposes the corresponding peak-to-background ratios were: 4.4, 7.1 and 7.9 for 5kV, 10kV and 15kV, respectively. In addition to Nb, other elemental peaks could be detected from the surrounding materials. The Al and Si peaks were generated from the holder (the O peak was visible due to oxidation of the holder itself), the Ni peak originated from the sample grid and the extraction

The crystal structure is a member of the hexagonal crystal system and consists of tetrahedrally coordinated Zinc and Sulfur atoms that are stacked in an ABABAB pattern.
The structure is closely related to the structure of lonsdaleite, or hexagonal diamond.
As there all orientations of the crystal, rings of different 2θ values are formed
