Without the presence of any catalysts or templates, single-crystal zinc sulfide (ZnS) nanotubes have been successfully synthesized in bulk quantity by a facile and controllable process based on thermal evaporation of ZnS powders. X-ray diffraction (XRD), energy dispersed X-ray spectrometry (EDS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and selected area electron...
Vertically aligned ZnO nanowire arrays were grown on ZnO single crystals using a chemical vapor deposition method. Nucleation sites were defined by patterning Au nanodot catalysts fabricated through anodized aluminum oxide (AAO) templates. Morphology and structure characterizations showed that the as-grown nanowires had the single-crystal hexagonal wurtzite structure with a <0001> growth direction...
