We present an analysis of the interatomic force of Ni nanowires on the basis of the interatomic interaction potential energy curve, which is obtained from the results of in situ high temperature X-ray diffraction in the range of 25–800 °C. Compared with bulk Ni, Ni nanowires have larger interatomic force. Our research offers a simple method of studying the mechanical properties of the nanowires.
Based on our experimental results that the interaction potential energy curve of nanowires is much steeper than that of the bulk Ni, we can know that the interaction force between atoms for Ni nanowires is greater than that for the bulk Ni. The reduction of the coordination numbers of surface atoms for Ni nanowires may make the interatomic force stronger.Figure optionsDownload as PowerPoint slide
