http://www.webreview.dz/ Webreview est un site fédérateur des revues scientifiques. Il met à la disposition des utilisateurs un ensemble de revues scientifiques algériennes couvrant tous les domaines. Webreview est ouvert à toute revue désireuse de publier son contenu en ligne soit en mode d'accès complet ou restreint permettant ainsi la valorisation de la recherche scientifique en Algérie. Webreview et un projet développé par le CERIST au sein de la Division Recherche et Développement en Sciences de l'Information.

Thin films Spray pyrolysis ZnO:Fe Resistivity Band gap energy <p>We present the influence of Fe-doping (2%, 3% and 4%) on ZnO thin films. For this purpose, structural, electrical and optical proprieties have been investigated by X-ray diffraction, 4-points technique and UV-Visible spectrophotometry. The ZnO:Fe thin films have been deposited by pneumatic spray pyrolysis on glass substrates at different temperatures (350, 400 and 450°C) and fixed molarity (0.1mol/l). The precursor solution is a mixture of zinc acetate dihydrate (Zn(CH3COO)2, 2H2O) and iron (...)</p> - <a href="http://www.webreview.dz/spip.php?rubrique387" rel="directory">Numéro 02</a> / <a href="http://www.webreview.dz/spip.php?mot2036" rel="tag">Thin films</a>, <a href="http://www.webreview.dz/spip.php?mot8360" rel="tag">Spray pyrolysis</a>, <a href="http://www.webreview.dz/spip.php?mot8361" rel="tag">ZnO:Fe</a>, <a href="http://www.webreview.dz/spip.php?mot8362" rel="tag">Resistivity</a>, <a href="http://www.webreview.dz/spip.php?mot8363" rel="tag">Band gap energy</a> <div class='rss_chapo'><p>We present the influence of Fe-doping (2%, 3% and 4%) on ZnO thin films. For this purpose, structural, electrical and optical proprieties have been investigated by X-ray diffraction, 4-points technique and UV-Visible spectrophotometry. The ZnO:Fe thin films have been deposited by pneumatic spray pyrolysis on glass substrates at different temperatures (350, 400 and 450°C) and fixed molarity (0.1mol/l). The precursor solution is a mixture of zinc acetate dihydrate (Zn(CH3COO)2, 2H2O) and iron chloride hexahydrate (FeCl3, 6H2O) dissolved in bi-distilled water. The X-ray diffraction (XRD) analyzes show that all the prepared thin films have a polycrystalline structuredominated by (100), (002) and (101) textured orientations. A resistivity of 2.9 10-2 Ω.cm was found for films deposited at 450°C with an iron rate of 3%. The average transmittance was found to be in the range of 45-70% for the different doping rates. The optical band gap energy of the films was found near 3.3 eV.</p></div>
