Abstract
- Palladium nanowires are good candidates for hydrogen sensing due to the many advantages. In this paper, we discuss the controlled growth of palladium nanowires into the nanopores of anodized alumina oxide (AAO) via template-assisted electrodeposition. This technique provides precise control for the dimensional growth of Pd nanowires. The potential range for electrochemical deposition of palladium nanowires was determined by Linear Sweep Voltammetry (LSV). Crystallinity and microstructural studies of the palladium nanowires were carried out using X-ray diffractometry (XRD) and scanning electron microscopy (SEM) as characterization tools. Systematic study on nanowire alignment across 3 µm-gaps between pairs of microfabricated gold electrodes was carried out using a.c. dielectrophoresis technique. Optimized conditions for good nanowire alignment were reported.
