Sol-gel derived multilayer ZnO thin films were successfully prepared by spin coating technique on glass, Si wafer and platinum substrates. Structural and morphological features of the samples were investigated by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) analysis. The combined techniques assess that uniform flawless films with preferable c-axis orientation of...
Transverse optical confinement in zinc oxide (ZnO) random cavities on Si substrate is achieved by a self-generated zinc silicate (Zn2SiO4) layer formed between the interface of ZnO and Si after thermal annealing.
We have synthesized Mn-doped ZnO thin films by inkjet printing using a two-step annealing process at 200??C for the decomposition of the organic compounds, and at various temperatures above 400??C to tailor room temperature ferromagnetism. Highly c axis oriented 80 to 400 nm thin films on (001) Si substrates are obtained with a magnetic moment as large as 2.1??B/Mn2+. X-ray absorption and emission...
In this paper, ZnO nanorods were synthesized by the hydrothermal process on various substrates such as glass, ITO, p-type porous silicon and n-type porous silicon by dipping in ZnO solution and atomic layer deposition method. The thin films a grown on substrates were washed with deionized water to eliminate residual salts, dried in air, and annealed at 400 degC. Scanning electron microscopy and X-ray...
The aim of the work was to study the effect of postgrowth thermal annealing processes on the characteristics of the zinc oxide films grown on silicon substrates by dc reactive magnetron sputtering. The growth temperature of the ZnO thin films was fixed at 230degC and then the samples were annealed in dry air atmosphere at 800degC for one hour. The surface of the ZnO samples was analyzed with a scanning...
