**2.1 Ion beam-induced morphological changes in silver nanowires**

The morphological image of un-implanted Ag-NWs is presented in **Figure 1(a)**. The morphology shows long-shaped Ag-NWs. After 5 MeV, carbon ions

implantation at the dose of 5 × 1014 ions/cm2 , Ag-NWs diffused at the junction points, as shown in **Figure 1(b)** [30]. At high ion dose of 1 × 1016 ions/cm2 , Ag-NWs start to be sliced, i.e., reduce the diameter and finally cut the nanowires as shown in **Figure 1(c**, **d)**, respectively [30].
