摘要
Silver nanodendrite has gained the interest of scholars because of its broad range of applications for its unique features. The growth of nanodendrites typically takes place at the epitaxial intra-dendrite interface between the single-crystal primary and secondary dendrites. In this paper, we reported for the first time a newly identified “non-epitaxial” intra-dendrite interface in silver nanodendrites. The silver nanodendrites were fabricated using a water drop electrodeposition method to induce electrochemical migration in pure water solution under applied bias. The non-epitaxial intra-dendrite interface featured a peculiar 3–5 nm helical nano-yarn structure which can support the growth of a high-volume secondary dendrite due to its interfacial strengthening characteristic. The volume or mass supported through the non-epitaxial intra-dendrite interface was 282 times greater than the one through the typical epitaxial one. This study is believed to give new understandings of the non-epitaxial dendrite growth via nano-yarn bundling and its strengthening mechanism.
