Wetting Method

Silver nanostructures were synthesized by a template wetting method throughout decomposition of silver acetate. The morphology and activation energy of silver nanostructures were investigated. The activation energy from silver acetate to silver particles can be evaluated by Friedman method, which is dependent of the decomposition process, and the activation energy was estimated in the range between 355 and 400 kJ/mol. The template wetting method utilizing the decomposition of silver acetate can be applied to produce a silver nanostructured material with high functional properties.

Palladium Metal

The palladium nanotube was synthesized by template wetting and annealing process. And the activation energy for formation of the palladium metal from palladium acetate was evaluated. The activation energy was evaluated by Friedman method and the values were in the ranges between 65 and 98 kJ/mol. The diameters and lengths of synthesized palladium nanotubes ranged from 130 to 190 nm and from 2 to 3 μm, respectively. The palladium nanotubes can be successfully fabricated by the template wetting process, and the crystalline structure is confirmed by XRD. From DSC results the thermal decomposition of precursor containing palladium acetate/PLLA occurred at 248°C, which corresponds to the precipitation of palladium metal.

AbstractWe report monolithic integration of indium arsenide (InAs) nanorods and zinc oxide (ZnO) nanotubes using a multilayer graphene film as a suspended substrate, and the fabrication of dual-wavelength photodetectors with the hybrid configuration of these materials. For the hybrid nanostructures, ZnO nanotubes and InAs nanorods were grown vertically on the top and bottom surfaces of the graphene films by metal-organic vapor-phase epitaxy and molecular beam epitaxy, respectively. The structural, optical, and electrical characteristics of the hybrid nanostructures were investigated using transmission electron microscopy, spectral photoresponse analysis, and current–voltage measurements. Furthermore, the hybrid nanostructures were used to fabricate dual-wavelength photodetectors sensitive to both ultraviolet and mid-infrared wavelengths.

ABSTRACTThe growth of ZnO nanotubes and nanosquids is obtained by conventional thermal chemical vapor deposition (CVD) without the use of catalysts or templates. Characterization of these ZnO nanostructures was conducted by X-ray powder diffraction (XRD), Field-emission scanning electron microscopy (FESEM), Raman spectroscopy, and photoluminescence (PL). Results indicate that these ZnO nanostructures maintain the crystalline structures of the bulk wurtzite ZnO crystals. Our results show that rapid cooling can be used to induce the formation of ZnO nanotubes and ZnO nanosquids. The self-assembly of these novel ZnO nanostructures are guided by the theory of nucleation and the vapor-solid crystal growth mechanism.
