利用射频磁控溅射方法,首次合成了具有单侧羽毛状的多级并联结硼纳米线.硼纳米线分枝在主干的同一个侧面形核和生长,形成并联的Y型或是T型纳米结,主干的直径在60~80nm,而分枝的直径在20~40nm.分枝和分枝之间、主干和主干之间、分枝和主干之间,全部自组织成排列规则、高度取向的列阵,在羽毛状硼纳米线的形成和自取向过程中,没有涉及到任何的模板和触媒.我们相信通过优化实验条件和改变靶的成分等,采用同样的方法可以制备一系列的不同纳米线或是纳米管之间的异质结.
Using radio-frequency magnetron sputtering method, a multi-level parallel-bonded boron nanowire with unilateral feather shape was synthesized for the first time.The boron nanowire branches nucleate and grow on the same side of the trunk to form parallel Y- or T-type Nodules, the diameter of the trunk in the 60 ~ 80nm, and branches in the diameter of 20 ~ 40nm. Branches and branches, between the trunk and trunk, branches and trunk, all self-organized into rules, height The alignment of the array does not involve any template or catalyst during the formation and self-orientation of the feathery boron nanowires and we believe that by optimizing the experimental conditions and changing the composition of the target, we can use the same method to prepare a series of Heterojunction between different nanowires or nanotubes.
