Abstract

Synthesis, characterization and integration of single metallic nanowires with enhanced electrical and mechanical properties into plastic substrate is a vital task for the development of transparent/flexible electronics as well as nanosensors. Among metallic nanowires, heterogeneous core-shell nanowires can provide benefits of more than one nanowire material and thus create unique properties to solve the drawbacks of respective nanowire materials. In this paper, we will show synthesis, electrical characteristics, and integration of a new FeNiCo-Au core-shell nanowire consisting of a mechanically strong FeNiCo core and highly conductive Au shell, promising both enhanced mechanical properties and electrical conductivity. A home-built alignment system based on an optical microscope and a xyz piezo positioner was developed to transfer individual nanowires into microelectrodes formed in plastic substrate. Electrical conductance of single FeNiCo-Au core shell nanowires was measured using the two-probe electrodes. The results were compared to that of FeNiCo nanowires. By decoupling the conductance through respective FeNiCo core and Au shell in the FeNiCo-Au core shell nanowire, the conductance of the Au shell was obtained.
