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.
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.
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 ...
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 ...

The Schottky contact must be formed between the counter electrode and the tip of the nanowire since the ohmic contact will neutralize the electrical field generated at the tip. ZnO nanowire with an electron affinity of 4.5 eV, Pt (φ = 6.1 eV), is a metal sometimes used to construct the
Classic Beef Stroganoff. A nod to tradition, with a tip of the hat to the ’80s love of decadent meals, beef Stroganoff seemed destined for popularity.
