Figure 1From: Fabrication and Properties of Ag-nanoparticles Embedded Amorphous Carbon Nanowire/CNT HeterostructuresSEM images of CNTs doped by energetic Ag ions at different doses; a Cross-sectional image of as-grown CNT array; b Cross-sectional image of the nanoarray doped at 3 × 1016 cm−2; c Cross-sectional image of the nanoarray doped at 1 × 1017 cm−2; d–f are the top morphologies corresponding to samples in a, b and c, respectively. These cross-sectional SEM images of the nanoarray show well-aligned structures before and after ion implantation. Ag ion implantation with lower dose induces lot of changes in the top microstructures of nanoarrays. However, high-dose ion implantation makes carbon nanonet to be formedBack to article page
