Two unique helical zinc gallate (ZnGa2O4) nanostructures were synthesized by thermal evaporation using the zinc selenide (ZnSe) nanowires; helical ZnGa2O4 nanowire rolls either on a straight ZnSe nanowire support or without any support. They all consist of single-crystalline cubic ZnGa2O4 crystals without any dislocation over the entire helical structure and have four equivalent growth directions of 011 with the axial direction of [001]. We suggest that the lattice matching with the ZnSe nanowires would be an important factor in determining the growth direction of the helical ZnGa2O4 nanowires.
利用硒化锌（ZnSe）纳米线通过热蒸发合成了两种独特的螺旋状镓酸锌（ZnGa2O4）纳米结构；螺旋状的ZnGa2O4纳米线卷要么附着在笔直的ZnSe纳米线载体上，要么没有任何载体。它们均由单晶立方ZnGa2O4晶体组成，在整个螺旋结构上没有任何位错，并且具有与[001]轴向等效的四个011生长方向。我们认为，与ZnSe纳米线的晶格匹配将是决定螺旋状ZnGa2O4纳米线生长方向的一个重要因素。
