Quantum conductance of copper nanowires — •Saeideh Mohammadzadeh1, Davoud Pouladsaz2, Reinhard Streiter1, and Thomas Geßner1 — 1Zentrum für Mikrotechnologien, Technische Universität Chemnitz — 2Institut für Physik, Technische Universität Chemnitz
Electronic transport properties of the Cu nanowires are studied using theoretical analysis based on non-equilibrium Green function’s technique within the density functional tight-binding method. The systems, presented in this work, consist of Cu nanowires in various crystalline directions, coupled between semi-infinite copper electrodes. The current-voltage characteristics of the wires and charge density with non-equilibrium conditions are investigated as well.
