文摘

Electron tomography and high-resolution transmission electron microscopy were used to characterize the unique three-dimensional structuresof helical or zigzagged GaN, ZnGa₂O₄, and Zn₂SnO₄ nanowires. The GaN nanowires adopt a helical structure that consists of six equivalent<0gif">11> growth directions with the axial [0001] direction. We also confirmed that the ZnGa₂O₄ nanosprings have four equivalent <011> growthdirections with the [001] axial direction. The zigzagged Zn₂SnO₄ nanowires consisted of linked rhombohedrons having the side edges matchedto the <110> direction and the [111] axial direction
