Synthesis of Heterostructured Cu-Ni Nanowires — •Ziyi Wang, Tim Lehmann, Samuel Griffiths, Efi Hadjixenophontos, and Guido Schmitz — Institute of Materials Science Chair of Materials Physics, Heisenbergstr. 3, 70569 Stuttgart, Germany

In recent years, nanowires have been widely applied in electronic devices such as transistors and batteries due to their outstanding electrical conductivity and miniscule size. This work involves the research of phase stability of Cu-Ni nanowires, in order to determine whether heterostructured nanowires can form by annealing from the single phase solid solution. The whole work is separated into three steps. First, binary nanowires are prepared by electrodeposition using a porous membrane as a template. Second, different heat treatments are conducted at temperatures ranging from 130°C - 600°C in order to induce phase separation. Finally, SEM, TEM as well as EDX are utilized to analyze the nanowires. For a better understanding, Atom Probe Tomography (APT) is suggested for a 3D reconstruction of the nanowires.
