  2. Zinc oxide nanostructure - Wikipedia

    en.wikipedia.org/wiki/Zinc_oxide_nanostructure

    ZnO creates one of the most diverse range of nanostructures, and there is a great amount of research on different synthesis routes of various ZnO nanostructures. [1] The most common methods to synthesise ZnO structures is using chemical vapor deposition (CVD), which is best used to form nanowires and comb or tree-like structures.

  3. Zinc oxide nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Zinc_oxide_nanoparticle

    ZnO is a wide-bandgap semiconductor with an energy gap of 3.37 eV at room temperature. [1] ZnO nanoparticles are believed to be one of the three most produced nanomaterials, along with titanium dioxide nanoparticles and silicon dioxide nanoparticles. [2] [3] [4] The most common use of ZnO nanoparticles is in sunscreen.

    The diameter of the nanowire which is grown depends upon the properties of the alloy droplet. The growth of nano-sized wires requires nano-size droplets to be prepared on the substrate. In an equilibrium situation this is not possible as the minimum radius of a metal droplet is given by [ 4 ]

  5. Graphite-like zinc oxide nanostructure - Wikipedia

    en.wikipedia.org/wiki/Graphite-like_zinc_oxide...

    Most of the synthesized Zinc oxide (ZnO) nanostructures in different geometric configurations such as nanowires, nanorods, nanobelts and nanosheets are usually in the wurtzite crystal structure. However, it was found from density functional theory calculations that for ultra-thin films of ZnO, the graphite-like structure was energetically more ...

  6. Nanowire - Wikipedia

    en.wikipedia.org/wiki/Nanowire

    Most synthesis techniques use a bottom-up approach. Initial synthesis via either method may often be followed by a nanowire thermal treatment step, often involving a form of self-limiting oxidation, to fine tune the size and aspect ratio of the structures. [7] After the bottom-up synthesis, nanowires can be integrated using pick-and-place ...

  7. Nanorod - Wikipedia

    en.wikipedia.org/wiki/Nanorod

    Zinc oxide (ZnO) nanorod, also known as nanowire, has a direct bandgap energy of 3.37 eV, which is similar to that of GaN, and it has an excitation binding energy of 60 meV. The optical bandgap of ZnO nanorod can be tuned by changing the morphology , composition, size etc.

  8. Zinc oxide - Wikipedia

    en.wikipedia.org/wiki/Zinc_oxide

    Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...

  9. Gallium nitride nanotube - Wikipedia

    en.wikipedia.org/wiki/Gallium_nitride_nanotube

    The ZnO nanowire templates are then removed by thermal reduction and evaporation. An analysis using transmission electron microscopy (TEM) shows that ZnO residue, along with a thin film of porous GaN, is still found in the upper portion of the nanotubes after the templates are removed. This is a result of zinc and oxygen coming off of the ...
