An elongated structure with nanoscale transverse dimensions. Crystal structure, growth direction, sidewall facets and surface chemistry determine its properties and morphology.
A solution route in which a polyol serves as solvent and reducing medium for metal nucleation and growth. For silver wires, controlled seed structure and capping chemistry can favour axial growth. Temperature, reduction rate, seed population, halides, oxygen and ligand coverage act together; the method is not defined by a single universal recipe.
A high-aspect-ratio silver structure with nanoscale cross section. Low intrinsic metal resistivity and sparse network connectivity make such wires useful for flexible transparent conductors, but nanowire junction resistance, insulating ligands, tarnish and mechanical connectivity can dominate device performance.
A silver wire composed of five twinned fcc domains around its axis, commonly with a pentagonal cross section. Sidewall passivation and atom addition at ends can favour one-dimensional growth from a multiply twinned seed. Cross-sectional microscopy and diffraction are stronger evidence for this structure than the outer wire outline alone.[ref]

A nanowire is a nanoscale wire with a diameter typically on the order of nanometers (1 to 100 nanometers) and can be made from a variety of materials, including metals, semiconductors, and insulators. These materials exhibit unique electrical, optical, and mechanical properties at the nanoscale, making nanowires of great interest in a variety of scientific and technological fields.
