Structural and electronic properties of zinc oxide nanostructures via density functional theory

Structural and electronic properties of zinc oxide nanostructures via density functional theory

By using ab initio density functional theory we studied the structural and electronic properties of zinc oxide, monolayer, double layer graphenlike and nanoribbons with armchair and zigzag edges. In case the double layer, the effects of inter-layer coupling on the electronic structures, were observed. These results showed that the energy gap in the monolayer was closed by inter-layer coupling. It was found that the ZnO double layer has a metallic behavior. Our results showed zigzag ZnO ...

CTAB-Assisted of Zinc Ferrite Nanocrystals Prepared by Simple Co-Precipitation Synthesis

Zinc ferrite (Fe2O3/ZnO) nanocomposites were successfully synthesized by simple co-precipitation method via iron (III) nitrate 9-hydrate (Fe(NO3)3.9H2O) and zinc nitrate hexahydrate (Zn(NO3)2.6H2O) as precursor in the presence of cetyltrimethylammonium bromide (CTAB) surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM), X-ray diffraction (XRD), X-ray florescence (XRF) and Fourier transform ...
