Abstract
Ultrathin Au nanowires (AuNWs) and tadpole-shaped nanowires are synthesized on graphene oxide (GO) sheet templates. For the first time, 1.6 nm-diameter AuNWs are shown to contain hexagonal close-packed (hcp) crystal domains, and the tadpole-shaped nanowires exhibit alternating sets of hcp and face-centered cubic (fcc) structures, associated with variation in wire thickness.
摘要
在氧化石墨烯（GO）片模板上合成了超薄金纳米线（AuNWs）和蝌蚪形纳米线。首次发现 1.6nm 直径的 AuNWs 含有六方密堆积（hcp）晶畴，而蝌蚪形纳米线则表现出交替的 hcp 和面心立方（fcc）结构，与线厚度的变化有关。
