Caracterização da alteração hidrotermal micácea do tipo greisen e dos reequilíbrios de baixa temperatura em áreas graníticas : o exemplo do Distrito Estanífero de Encruzilhada do Sul, RS
(2007) [Artigo de periódico]The hydrothermal alteration associated with the tin mineralization in the Encruzilhada do Sul Tin District is characterized by zones with different compositions. The most important of these hydrothermal zones are the phyllic ... -
Effect of annealing atmosphere on the structure and luminescence of Sn-implanted SiO/sub 2/ layers
(2005) [Artigo de periódico]Sn nanoclusters are synthesized in 180 nm SiO2 layers after ion implantation and heat treatment. Annealings in N2 ambient at high temperatures sTù700 °Cd lead to the formation of Sn nanoclusters of different sizes in ... -
Formation of epitaxial [Beta]-Sn islands at the interface of SiO/sub 2/Si layers implanted with Sn ions
(2005) [Artigo de periódico]180 nm SiO2 layers on Si s100d were implanted with Sn ions producing a profile with a peak concentration of 3 at. % at the middle of the oxide. After high temperature s900–1100 °Cd annealing, an array of b-Sn islands ...
