Preparation Of Alloy Nanowire Arrays Based On Template-method And Their Electronic Transport Behavior In The Melting Process

With the rapid development of nanomaterials and nanotechnology, the highly integratedelectronic devices are put forward higher requirements on the circuit transfer materials.Therefore, the research of one-dimensional metal nanomaterials, especially one-dimensionalalloy nanomaterials, as the foundation of nanoelectronic devices have a very importantsignificance. This also becomes one of the most Cutting-edge and hot research topics in thefield of nanodevices. In this paper, we mainly demonstrate a new fusion method of fabricatingone-dimensional alloy nanowire arrays based on the porous anodic aluminum oxide (AAO)template. We have synthesized three kinds of alloy nanowire arrays, analyzed them by kindsof characterization means, and measured the electronic transport property in the meltingprocess. The results of experiments indicate that it can be synthesized the compositioncontrollable and homogeneous alloy nanowire arrays using this new method. The maincontents of this article are as follows:Firstly, PbBi alloy nanowire arrays are obtained by melting Pb/Bi multilayer nanowirearrays which are prepared using dual slots electrodeposition based on the AAO template. Weuse X-ray diffraction, field emission scanning electron microscope, transmission electronmicroscopy and energy dispersive spectrometer elemental mapping to characterize andobserve the morphology, structure and composition of the samples. The results show that thesynthetical PbBi alloy nanowire arrays have uniform composition using this new fabricationmethod.Secondly, we have prepared ZnPb alloy nanowire arrays with different proportion bychanging the deposition time of Zn or Pb parts. Besides, we have also prepared AgZn alloynanowires which contain a high melting point metal by long-time melting at the temperatureslightly higher than the melting point of another metal. This demonstrates that the newmethod has the superiority of controlled composition and universality.Thirdly, in the molten process, the electronic transport property of nanowire arrays ismeasured using two-electrode method by SourceMeter instrument. The results show that theresistance trends with temperature changes actually reflects the changes of the compositionand structure in the alloy nanowires. And this can provide the related experimental datas toanalysis the formation process of alloy nanowires.
