Calculating the electrical Conductivity of metal nanowires
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 5, Issue 11
Abstract
Quantum properties of electrons inside atoms and their interaction with each other are important at the nano scale. By the production of nanostructures, we can control the intrinsic properties of materials including melting temperature, magnetic properties, load capacity and even color without changing the chemical composition of the material. Development in the field of power electronics is dependent on the continued progress in the production of nano materials. The conductivity is the main properties of metallic nanowires. In this paper, tensor conductivity will be introduced for low-dimensional electron. according to the particle-in-a-box model and diagonal approximation solution, the conductivity tensor components are calculated for nanowires, ( f d ~? ? Fermi wave length for the bulk metal and ādā is the diameter of the nanowire). Fermi level in the small diameter wires significantly vary with the Fermi level in the bulk metal. For the mass of metal, the Fermi level of a metal mass is used to find the number of sub-bands, while for the nanowires, depending on the size of the Fermi level is determined by the number of sub-bands. In the follow, conductance of metal nanowires is Conductivity.
