Although there is a number of theoretical and experimental studies to investigate several properties of AuNWs. There are no specific study on the strain influenced electronic, structural properties. Additionally, the electronic transport properties of monoatomic AuNW have not been reported yet. Therefore, we have presented the first principal calculation to fulfill the study gap and present it systematically in this paper. tronic Simulations with Thousands of Atoms(SIESTA) code . Transport properties are performed within the non-equilibrium Green's function theory as developed in the TranSIESTA module. The pseudopotential is constructed by using Troullier Martins Method . The generalized gradient approximation (GGA) function with Perdew-Burke-Ernzerhof(PBE) is adopted to treat the effects of correlation and electronic exchange. In all the calculations, we used the Double Zeta Plus polarization (DZP) as basis sets. Monkhrost pack scheme has been used for Brillouin zone integration by using 1x1x100. An energy cutoff of 300 Ry is used for the expansion of the reciprocal space. The electron temperature was set equal to 300 K with a Fermi surface broadening. The atomic relaxation was achieved when the force reached the value of 0.002 eV/ Å using the standard conjugate-gradient (CG) technique. The convergence criteria for the energy of the self-consistent field is set to be 1.0x10 -5 Å. The vacuum gap of 25 Å between adjacent chains in x and y directions has been used to prevent interactions between the adjacent unit cell. For transport properties calculation, we have determined the current through the scattering region sandwiched between two semi-infinite electrodes at a finite bias voltage using the Landauer-Bttiker formula .
