Mn-doped ZnO thin films with different percentages of Mn content (0, 1, 3 and 5 at%) substrate temperature 350 °C, were deposited by a simple ultrasonic spray pyrolysis method under atmospheric pressure. The chemical compositions surface morphologies examined dispersive x-ray spectroscopy scanning electron microscopy micrographs. We have studied the structural optical properties using diffraction (XRD), Raman spectroscopy, Fourier transform infrared ultra-violet visible near-infrared...
Our work focuses on the study of electronic structure undoped and K-doped ZnO using density functional theory as implemented in Wien2k package.Generalized gradient approximation GGA plus Tran-Blahamodified Becke-Johnson (TB-mBJ) were used to calculate exchange-correlation energy.From properties, has a direct band gap (Γ -Γ ) direction with value 0.76 eV within 2.63 + TB-mBJ.For (12.5%) was found be 1.15 3.28 TB-mBJ, we have observed that an emersion new narrow exists valence which is mainly...
In this paper, we have investigated the structural, electronic and optical properties of alkaline earth oxides MO (M = Be, Mg, Ca, Sr, Ba) using full-potential linearized augmented plane wave method (FP-LAPW) within framework density functional theory (DFT), as implemented in Wien2k package generalized gradient approximation (GGA) GGA plus Tran Blaha modified Becke Johnson potential (TB-mBJ) for treating exchange correlation effects. The main objective work is to introduce first principal...
The contaminated rejects due to the rise of textile and dye industry have dramatically affected ecosystem aquatic reserves. In addition, decontamination organic species based on nanoparticles as photocatalyst is considered a complicated route material consumer. To address separation issue, it necessary develop new methods degrade dyes through coast effective processes. this context, we present in our study photocatalysis design by implementation inner side surface transparent glass tube one...
