The texture as well as epitaxial growth of intermetallic compounds (IMCs) are becoming important issues, due to increases in IMCs-solder ratios in the development of micro-bumping. (Cu, Ni)6Sn5 formed on Ni substrate didn't simply grow in an unexpected manner, but did so, producing a spectacular morphology. Even in the presence of very few Ni atoms dissolved in (Cu, Ni)6Sn5, a strongly preferential...
Ag-Cu nanoalloy has been synthesized directly in solution. The composition, morphology and structure of the Ag-Cu nanoalloys were characterized by XRD, TEM, EDS and SEM. The morphology of Ag-Cu nanoalloys appears small, uniform, and spherical. The size distribution mainly focuses on 80nm~90nm. An average composition is Ag48.9Cu51.1, which is within experimental error of the nominal 1:1 stoichiometry...
In this paper, highly dispersed copper oxide (CuO) nanoparticles with different size and morphology have been successfully prepared by a quick-precipitation method in DMAC-water mixed solvent. The as-prepared CuO nanoparticles were characterized by high resolution transmission electron microscopy (HRTEM) and x-ray diffraction (XRD). Several kinds of CuO particles with different morphology were obtained...
Zinc oxide nanowire networks have been prepared using evaporation/condensation technique with a modified set-up that allows the control of the doping present in the gas phase during the growth. The doping process has been studied for the development of homo-junctions. ZnO nanowires with uniform copper addition first and then non-uniform doping distribution have been prepared. Morphology, crystalline...
