Filmes de óxido de índio dopado com estanho depositados por magnetron sputtering.

Abstract: Ao amigo e conselheiro Prof. Dr. Roberto Koji Onmori, que esteve presente desde o início, sempre que precisei, e sem o qual eu talvez não tivesse seguido o caminho que escolhi. Ao Prof. Dr. Marcos Massi, pelo carinho e atenção dispensados no meu Exame de Qualificação. Ao Prof. Dr. Jose Fernando Diniz Chubaci do LACIFID-IFUSP, por todo o apoio técnico e moral. Ao Prof. Dr. Luis da Silva Zambom, pela ajuda geral, tanto na utilização da sala limpa quanto em métodos de caracterização. Aos técnicos do LSI-EPUSP Nel… Show more

“…Pure indium (In) oxide without doping of tin (Sn) is considered a material with electrical insulator property, but, when it is modified with oxygen vacancies, there is the possibility to reach high levels of n type (negative material), due its intrinsic defects 21 . When doped with Sn, this material becomes an impurity donor, because it is a tetravalent element (Sn) doped with a trivalent chemical element (In) 22 . Then, two mechanisms are possible to occur to generate electrical conduction in ITO thin films, such as:…”

“…Although the tin doping improves the electrical characteristic of ITO, there is a limit value that can be used in the material, because there is reduction of Hall mobility, and it considerably causes the decrease of transmittance. Studies report that the best proportion is 10 mol% of tin and 90 mol% of In oxide 22,23 . Another factor that interferes on the optical and electrical characteristics of ITO is the technique used to fabricate the thin films and also to process the parameters (including the chamber geometry and accessories) used during the deposition.…”
