The growth and structural study of Nickel doped Cobalt ferrite thin films on glass substrate using spray pyrolysis technique have been done. The structural studies confirmed the growth of polycrystalline film having cubic structure with Fd3m space group. The x ray density was found to increase with Ni concentration, where as the reduction, in crystalline size, was found in XRD m...

Zinc oxide thin films have been obtained on bare and GaN buffer layer decorated Si (111) substrates by pulsed laser deposition (PLD), respectively. GaN buffer layer was achieved by a two-step method. The structure, surface morphology, composition, and optical properties of these thin films were investigated by X-ray diffraction, field emission scanning electron microscopy, infrared absorption s...

In this paper, Al-doped ZnO thin film transistors (AZO-TFT) were fabricated by the thermal evaporation growth of AZO channel layer on a silicon substrate at temperatures below 250°C. A SiO2 dielectric layer grown by the horizontal furnace was used as a gate. An active layer thickness of 10nm was measured by Atomic Force Microscopy (AFM), and its surface had root mean square (rms) roughness 12.6...

In DMS materials, a small fraction of a host semiconductor cation is substituted by magnetic ions. We chose as semiconducting host the transparent ZnO, with a bandgap of 3.3 eV at room temperature. Studies on ZnO doped with 3d transition metals indicated only small magnetic moments. The more recent results for Gd in GaN, indicating high magnetic moments, motivated us to investigate ZnO thin fil...

Investigation of new calculate depends on the controlled optical properties of nanomaterials. Understanding the growth mechanism and growth parameters of nanostructured materials is essential. ZnO is one of the most important semiconductor materials for its semiconducting characteristics. In the present paper, we investigated a new model by theoretical methods; it is based on correlation from t...

ZnO is an important II-VI semiconductor material for devices with possible applications such as piezoelectric transducers, gas sensors, transparent electronic in solar cell, saw devices. Based on known research, ZnO is the most promising in optoelectronic and optical applications, especially in UV region. An understanding of the optical properties of ZnO thin film on different substrates is als...

Zinc oxide [ZnO] thin films are deposited using a radiofrequency magnetron sputtering method under room temperature. Its crystalline quality, surface morphology, and composition purity are characterized by X-ray diffraction [XRD], atomic force microscopy [AFM], field-emission scanning electron microscopy [FE-SEM], and energy-dispersive X-ray spectroscopy [EDS]. XRD pattern of the ZnO thin film ...
