In this work, we report the synthesis and detailed structural characterization of novel helical gold-copper nanowires. The nanowires possess the Boerdijk-Coxeter-Bernal structure, based on the pile up of octahedral, icosahedral, and/or decahedral seeds. They are self-assembled into a coiled manner as individual wires or into a parallel-ordering way as groups of wires. The helical nanowires are ultrathin with a diameter of less than 10 nm and variable length of several micrometers, presenting a high density of twin boundaries and stacking faults. To the best of our knowledge, such gold-copper nanowires have never been reported previously.
在这项工作中,我们报告了新型螺旋状金-铜纳米线的合成和详细的结构表征。这些纳米线基于八面体、二十面体和/或十面体种子的堆积,具有 Boerdijk-Coxeter-Bernal 结构。它们以单个纳米线的螺旋方式或多个纳米线的平行排列方式自组装而成。这些螺旋状纳米线非常细,直径小于 10nm,长度可达数微米,具有高密度的孪晶界和位错。据我们所知,以前从未报道过这种金-铜纳米线。
