Title: Electron Transport in Gold Nanowires: Stable 1-, 2- and 3-Dimensional Atomic Structures and Non-Integer Conduction States
Published: September 14, 2011
Abstract: Experimental conductivity measurements made during highly stable tensile deformation of Au nanowires show a rich variety of behaviors, including non-integer quantum conductance plateaus, transitions and slopes. Using tight binding conductance calculations on simulated nanowires previously deformed using density functional theory, we demonstrate that all of these phenomena arise from structural transitions between highly stable ordered atomic configurations that self organize during tensile deformation.
