The Magnificent 1D material
Nanowire
Compared to the bulk counterparts, the outstanding properties of the one-dimensional (1D) metallic nanostructures have been taking attention for the last decades.
The optoelectronic properties of metallic nanowires strongly depend on the size of nanowires. As having at least sizes between 1 and 100 nm in dimension, demonstrate interesting optical, electrical, magnetic, and thermal properties due to the confinement effect.
When the size of the nanowire gets close to its electron mean free path, the resistivity of the nanowire increases due to the surface scattering of electrons. Although smaller diameter nanowires are less stable environmentally, they are advantages in terms of optical transmittance in optoelectronic applications.
Among other metallic nanowires, the silver nanowire is the most preferred nanostructure due to its physical properties since it holds high electrical (6.39 S/m) and thermal conductivity( 429 W/(m·K)) properties as inherited from the silver.
Hence, they are highly preferred in the applications of solar cells, touch screens, flexible sensors, and electromagnetic shielding.
