背景资料：Nanowires are one of the most promising nano-building blocks for a variety of applications, including nano-circuits, self-assembly, sensors/biosensors, nanoelectronics, solar cells, and energy devices. In this presentation, I will show the synthesis and fabrication of multisegmented nanowires using a template based electrodeposition method. These nanwires, with the diameter of 15-200 nm and length up 20 µm, are then characterized by SEM, TEM, EDAX, XRD, and electron diffraction. In my research group, several potential applications have been exhibited by these nanowires: (1) lead-free nanosolders have been successfully synthesized and are applied for nanowire assembly and nano-joint formation, which have great implications for nanoelectronics assembly and packaging; (2) doped tin oxide nanowires have been synthesized and are applied for sensor applications, which showed promise in detecting a variety of gas/vapor analytes at low concentrations; (3) (3) surface roughed platinum (Pt) nanowires, which was fabricated by controlling the electrodeposition current, have shown promise in high sensitivity electrochemical detection. These nanowires and self-assembling techniques have great potential in the integration of functional nanoelectronics and nanosensors.
