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.
Most types of molecular wires are derived from organic molecules. One naturally occurring molecular wire is DNA.Prominent inorganic examples include polymeric materials such as Li 2 Mo 6 Se 6 [1] and Mo 6 S 9−x I x, [2] [3] [4] [Pd 4 (CO) 4 (OAc) 4 Pd(acac) 2], [5] and single-molecule extended metal atom chains (EMACs) which comprise strings of transition metal atoms directly bonded to each ...
While not capable of the same scalability as single nanowire FETs, the use of pre-fabricated multiple nanowires for the channel increases reliability and reduces production costs since large volume printing processes may be used to deposit the nanowires at a lower temperature than conventional fabrication procedures.
Nanofabrication can be used to construct ultradense parallel arrays of nanowires, as an alternative to synthesizing nanowires individually. [ 3 ] [ 4 ] Of particular prominence in this field, Silicon nanowires are being increasingly studied towards diverse applications in nanoelectronics, energy conversion and storage.
Nanowires and nanotubes: The elastic moduli of some nanowires namely lead and silver, decrease with increasing diameter. This has been associated with surface stress, oxidation layer, and surface roughness. [62] However, the elastic behavior of ZnO nanowires does not get affected by surface effects but their fracture properties do.
A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery.Some designs (silicon, germanium and transition metal oxides), variations of the lithium-ion battery have been announced, although none are commercially available.
A network of carbon nanotubes has been used as a form of electronically conducting nanowires in the cathode of a zinc-carbon battery. Using nanotube ink, the carbon cathode tube and manganese oxide electrolyte components of the zinc-carbon battery can be printed as different layers on a surface, over which an anode layer of zinc foil can be ...
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.
