متن کاملAn experimental and theoretical study on the physical properties of Al doped ZnO thin films
In this research, ZnO thin films with Al impurity as dopant were coated onto cleaned glass substrates by the spray pyrolysis technique. Crystal structure of the thin films was studied via XRD, and UV-vis spectroscopy was carried out to investigate their optical properties. Finally, in order to study the effect of Al impurity in ZnO thin films, the band structures of both pure and doped systems ...
متن کاملTheoretical Verification Necessity of Leakage Currents Using Sm Doped Ceria Electrolytes in SOFCs
Numerous approaches have been made to solve the basic transport equation that describes a solid oxide fuel cell (SOFC) with mixed conduction. Classically, the open circuit voltage (OCV) is calculated with Wagner‘s equation, which is right within the limits of linear transport theory. In order to generalize Wagner’s equation, many models have been proposed to describe the current-voltage relatio...

0022-3093/$ see front matter 2008 Elsevier B.V. A doi:10.1016/j.jnoncrysol.2008.06.054 * Corresponding author. E-mail address: [email protected] (S. Lange). We obtained samarium-doped zirconia using two different routes. In one, atomic layer deposited thin crystalline films were doped by using ion implantation; this sample was mainly monoclinic. The other method, the skull-melting technique, y...
متن کاملOptical, Photoluminescence and Thermoluminescence Properties Investigation of ZnO and Mn Doped ZnO Nanocrystals
ZnO and ZnO: Mn nanocrystals synthesized via reverse micelle method. The structural properties nanocrystals were investigated by XRD and Transmission electron microscopy (TEM). The XRD results indicate that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. The various optical properties of these nanocrystals such as optical band gap energy, refractive index, dielectr...
