| Abstract Scope |
The synthesis of Cu-rich nanoclusters from single-crystal Cu nanowires via the application of Ar plasma etching will be reported. These clusters were synthesised at room temperature only in function of plasma exposure time. A detailed scanning transmission electron microscopy study was carried out in order to evaluate the effects of plasma exposure in Cu nanowires and the generated Cu-rich nanoclusters. Electron diffraction was used to assess possible phase transformations of the nanowires. Large surface-to-volume ratio induced chemisorption effects of residual active species in the plasma environment on the surface of Cu nanowires is considered to have a significant influence on their transformation to nanoclusters. |
