Nanowire

Nanowire

It can be defined as structures have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. Quantum mechanical effects are important and they are also known as "Quantum wires". Molecular nanowires are composed of repeating molecular units of either organic (e.g. DNA) or inorganic (e.g. Mo6S9-xIx).

Different types of nanowires are

Metallic (e.g., Ni, Pt, Au)

Semiconducting (e.g., Si, GaN)

Insulating (e.g., SiO2,TiO2).
