A nanowire is a nanostructure in the form of a wire with the diameter of the order of a nanometre (10 −9 m). More generally, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length.
A nanowire is a nanostructure with a diameter or thickness and width on the order of a nanometer (10−9 meters). Alternatively, nanowires can be defined as structures that have a width and thickness or diameter constrained to tens of nanometers or less and an unconstrained length.

In 2014, experimentalist successfully obtained PbO 2 nanowire through simple template electrodeposition. The performance of this nanowire as anode for lead-acid battery has also been evaluated. Due to largely increased surface area, this cell was able to deliver an almost constant capacity of about 190 mAh g −1 even after 1,000 cycles.
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.
The importance of the quantization is inversely proportional to the diameter of the nanowire for a given material. From material to material, it is dependent on the electronic properties, especially on the effective mass of the electrons. Physically, this means that it will depend on how conduction electrons interact with the atoms within a ...

Recent experiment on nanowire solar cells has led to a remarkable improvement of the power conversion efficiency of SiNW solar cells from <1% to >17% in the last few years. [5] The ability for lithium ions to intercalate into silicon structures renders various Si nanostructures of interest towards applications as anodes in Li-ion batteries ...
