Characterization of metallic electrical contacts to SnO2 thin films lightly doped with Eu3+ ions, and photo-induced resistivity
(Materials Chemistry and Physics, 2012-06-15) [Artigo]
Lightly Eu3+-doped (0.05%) SnO2 thin films are deposited by the sol-gel-dip-coating technique, topped by alternative metallic layers of Al, Sn or In, arranged in a parallel layout on the thin film surface, and deposited ...
Effect of pH of colloidal suspension on crystallization and activation energy of deep levels in SnO2 thin films obtained via sol-gel
(Journal of Physics and Chemistry of Solids, 2009-09-01) [Artigo]
Colloidal suspensions of tin dioxide (SnO2) are prepared by the sol-gel method from suspensions with distinct pHs. The particles in solution are embedded by an electrical layer. Decreasing the pH contributes to the destruction ...
Growth of Al2O3 thin film by oxidation of resistively evaporated Al on top of SnO2, and electrical properties of the heterojunction SnO2/Al2O3
(Journal of Materials Science, 2011-10-01) [Artigo]
Aiming for the investigation of insulating properties of aluminum oxide (Al2O3) layers, as well as the combination of this oxide with tin dioxide (SnO2) for application in transparent field effect transistors, Al thin films ...
Numerical simulation of the liquid phase in SnO2 thin film deposition by sol-gel-dip-coating
(Journal of Sol-Gel Science and Technology, 2010-09-01) [Artigo]
The fluid flow of the liquid phase in the sol-gel-dip-coating process for SnO2 thin film deposition is numerically simulated. This calculation yields useful information on the velocity distribution close to the substrate, ...
Nanoparticle characterization of Er-doped SnO2 pellets obtained with different pH of colloidal suspension
(Journal of Applied Physics, 2013-08-28) [Artigo]
SnO2:2 at. %Er xerogel samples were obtained by sol-gel technique from colloidal suspensions with distinct pHs. The evaluation of critical regions inside the nanocrystallite is fundamental for the interpretation of the ...
