The development of cost-effective and low-temperature synthesis techniques for the growth of highquality zinc oxide thin films is paramount for fabrication of ZnO-based optoelectronic devices, especially ultraviolet (UV)-light-emitting diodes, lasers and detectors. We demonstrate that the properties, especially UV emission, observed at room temperature, of electrodeposited ZnO thin films from c...

Highly transparent and conducting fluorine-doped ZnO (FZO) thin films were deposited onto glass substrates by radio-frequency (RF) magnetron sputtering, using 1.5 wt% zinc fluoride (ZnF2)-doped ZnO as sputtering target. Structural, electrical, and optical properties of the FZO thin films were investigated as a function of substrate temperature ranging from room temperature (RT) to 300°C. The cr...

ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...

The group-III elements, such as Al, Ga and In, are possible dopants for ZnO to improve the electric conductivity of ZnO thin film. Since Ga has lower cost than In and has higher oxidation resistance than Al, it becomes the preferred dopants for ZnO thin film for transparent conducting oxide (TCO) application. In the research, we used MOCVD method with Ga doping to prepare the Ga-doped ZnO thin ...

zno thin films with preferred orientation along the (002) plane were prepared onto the glass substrates by the sol-gel spin coating method for different post- annealing temperatures. the xrd study confirms that the thin films grown by this method have good crystalline hexagonal wurtzite structure. the optical band gap of the samples was determined from uv-visible spectra. it is found that the s...

Different zinc oxide (ZnO) nanostructured thin films were grown on glass substrates at low temperatures by combining successive ionic layer adsorption and reaction (SILAR) method and chemical bath deposition (CBD). Morphologies and structures of the samples were investigated by X-ray diffraction (XRD), energy-dispersive x-ray spectroscopy (EDX) and scanning electron microscopy (SEM). The reacti...

The sol-gel route has been applied to obtain ZnO-TiO2 thin films. For comparison, pure TiO2 and ZnO films are also prepared from the corresponding solutions. The films are deposited by a spin-coated method on silicon and glass substrates. Their structural and vibrational properties have been studied as a function of the annealing temperatures (400-750 °C). Pure ZnO films crystallize in a wurtzi...

Zinc oxide nanowires/nanobelts thin films were prepared by thermal evaporation deposition of Zn on two different kinds of substrates, namely Cr-glass and Cr-<100> n-type Si. ZnO nanostructured based COgas sensing thin films were formed, and the morphologies of these films were investigated by scanning electron microscopy (SEM). The sensing response of the films toward CO gas at operating temper...

Nanostructured ZnO thin films have been deposited using a successive chemical solution deposi method. The structural, morphological, electrical and sensing properties of the films were studied different concentrations of Al-dopant and were analyzed as a function of rapid photothermal proces temperatures. The films were investigated by X-ray diffraction, scanning electron microscopy, en dispersi...

Zinc oxide (ZnO) thin films have been widely investigated due to their multifunctional properties, i.e., catalytic, semiconducting and optical. They have found practical use in a wide number of application fields. However, the presence of a compact micro/nanostructure has often limited the resulting material properties. Moreover, with the advent of low-dimensional ZnO nanostructures featuring u...
