| Abstract: | Zn2SnO4 (ZTO) nanowires with a unique dendriticnanostructure were synthesized via a simple one-step thermalevaporation and condensation process. The morphology andmicrostructure of the ZTO nanodendrite have been investigated bymeans of field emission scanning electron microscopy (SEM), x-raydiffraction (XRD) and high-resolution transmission electronmicroscopy (HRTEM). SEM observation revealed the formation ofbranched nanostructures and showed that each branch exhibited aunique periodic structure formed by a row of overlaid rhombohedra ofZTO nanocrystals along the axis of the nanobranch. HRTEM studiesdisplayed that the branches grew homoepitaxially assingle-crystalline nanowires from the ZTO nanowire backbone. Apossible growth model of the branched ZTO nanowires is discussed. Tosuccessfully prepare branched structures would provide an opportunityfor both fundamental research and practical applications, such asthree-dimensional nanoelectronics, and opto-electronic nanodevices. |
