This paper reports the formation processes of crystalline Cd nanostructures (nanoparticles and nanowires) on ion-cut surfaces of cadmium niobate pyrochlores (Cd2Nb2O7). Irradiation with 3 MeV He+ ions has been performed at low temperatures (≤ 295 K) to induce material decomposition and aggregation of host atoms. The irradiation also leads to surface exfoliation due to rupture of gas (He and O2) filled blisters. Nanoparticles and nanowires are observed on the ion-cut surfaces at low and higher doses, respectively. The nanostructures are examined and characterized using a suite of experimental tools. Both the nanoparticles and nanowires are found to be single crystals that primarily consist of metallic Cd.
