我们通过在气相传输和冷凝沉积过程中添加合金元素（In或Sn），合成了三维自组装ZnO基纳米异质结构。每个三维纳米级异质结构由刻面纳米线芯组成，具有从中心纳米线芯的刻面发出的侧分支（纳米带或纳米棒）。中心纳米线芯可以是ZnO、（ZnO）（11）In2O3或In2O3，这取决于引入的焊剂组成比。分支的物理机制源于在纳米线芯的生长期间合金元素向刻面的偏析，从而产生用于侧分支的成核位点。(C)2003 Elsevier Science B.V.保留所有权利。
We have synthesized three-dimensional self-assembled ZnO-based nanoscale heterostructures through the addition of alloying elements (In or Sn) during the vapor phase transport and condensation deposition process. Each three-dimensional nanoscale heterostructure consists of a faceted nanowire core, with side branches (nanoribbons or nanorods) emanating from facets of the central nanowire core. The central nanowire core can be either ZnO, (ZnO)(11)In2O3, or In2O3, depending on incoming flux composition ratio. The physical mechanism of branching stems from segregation of alloying elements to facets during the growth of the nanowire core, thus creating nucleation sites for side branches.
