Phase transformation; structural and optical properties of two dimensional MoO3

Thin-layered materials from transition-metal dichalcogenides family and their preforms such as molybdenum three oxides (MoO3) exhibit great potential as active material in optoelectronics. Stable materials of few atoms thick have shown emerging capabilities in this area. In this article, we report the synthesis of MoO3 nanostructures by spray pyrolysis method. We will, perhaps for the […]

A systematic study on chemically deposited cadmium sulfide (CdS) thin film

AbstractIn this work, the conventional chemical bath deposition (CBD) technique and its growth parameters were systematically studied to deposit CdS thin films on the glass substrate. The samples were prepared using a simple aqueous solution containing cadmium sulfate (CdSO4·8H2O), thiourea [SC(NH2)2], ammonium sulfate [(NH4)2SO4] as a source of cadmium, sulfur, and a complexing agent, respectively. […]

Effect of plasma oxidation parameters on physical properties of nanocrystalline nickel oxide thin films grown by two-step method: DC sputtering and plasma oxidation

AbstractNanocrystalline nickel oxide (NiO) thin films were successfully grown on quartz substrates by two-step method. In the first step, nickel films were deposited on quartz substrates by DC magnetron sputtering technique. Then, the plasma oxidation of nickel films was used for preparation of nickel oxide. The effect of DC plasma power and treatment time on […]

Efficient single-layer light-emitting diodes based on organic–inorganic lead halide perovskite and tuning luminescence properties

AbstractBecause of the interesting features of the organic/inorganic halide perovskite (e.g., CH3NH3PbX3, X = Cl, Br) materials, such as long electron–hole diffusion length, high absorption coefficient and adjustable band gap, they have attracted a great deal of attention. In this research, CH3NH3PbX3 (X = Br, Cl) are synthesized and perovskite-based single-layer and perovskite-based bilayer diodes are fabricated. Using electron […]

Investigation morphological, electrical, and optical properties of Mn-doped ZnO thin film by sol–gel spin-coating method

AbstractIn this study, ZnO was doped with 0.01% Mn and it is grown on p-Si by the sol–gel spin-coating method. Obtained the thin film was studied that to understand the effect of 0.01% Mn-doping ratio on the optical and electrical properties of ZnO structure. In this context, first, the morphological structure of the thin film […]

Investigation of sensitivity and selectivity of ZnO thin film to volatile organic compounds

AbstractThis research addresses a detailed study on the sensitivity and selectivity of ZnO thin film to volatile organic compound (VOC) vapors that can be used for the development of VOC sensors. The ZnO thin film of 100 nm thickness was prepared by post-annealing of e-beam evaporated Zn thin film. The sample was structurally, morphologically, and chemically […]

On the corrosion resistance of AISI 316L-type stainless steel coated with manganese and annealed with flow of oxygen

AbstractAISI 316L-type stainless steel was coated with 300-nm-thick Mn thin films and post-annealed at 673 K with a constant flow of oxygen (250 cm3/min). The films crystallographic and morphological structures were analyzed using X-ray diffraction (XRD) and atomic force microscopy (AFM) before corrosion test and scanning electron microscopy (SEM) after corrosion test. Corrosion behavior of the samples […]

Antibacterial effect, structural characterization, and some applications of silver chiral nano-flower sculptured thin films

AbstractSilver chiral nano-flowers with 3-, 4-, and 5-fold symmetry were produced using oblique angle deposition method in conjunction with the rotation of sample holder with different speeds at different sectors of each revolution. X-ray diffraction, atomic force microscopy, and scanning electron microscopy were employed to obtain the nanostructure and morphology of the films. Their antibacterial, […]

Effect of substrate temperature on structural, morphological and optical properties of deposited Al/ZnO films

AbstractAl-doped ZnO (Al/ZnO) thin film is a promising alternative to an ITO electrode in solar cell applications due to its low price, non-toxicity and other promising properties. In this paper, Al/ZnO thin films at different substrate temperatures were deposited on glass substrates as transparent conducting (TCO) films by DC magnetron sputtering. The effect of substrate […]

Structural and optical properties of nanocrystalline α-MoO3 thin films prepared at different annealing temperatures

AbstractNanocrystalline α-MoO3 thin films were prepared successfully by thermal annealing of molybdenum (Mo) thin films deposited on quartz and silicon substrates using DC magnetron sputtering method. The influence of annealing temperatures ranging from 400 to 1,000 °C on the structural, morphological and optical properties of the prepared films was investigated by X-ray diffraction, Fourier transform infrared […]
