Mechanism of Metal Nanowire Formation via the Polyol Process

초록

The morphology and capping layer of Ag-nanowires prepared using the polyol process were examined to understand their formation mechanism. Cu-nanowires prepared from the salt reduction process were examined as well. The observation suggests that the nucleation and growth of the nanowires might have been controlled by thermodynamics, rather than by the kinetics of metal atom diffusion through the capping layer. In this study, a thermodynamic model was proposed to account for the limited radial growth of the nanowires during the process.
