incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...

Sputter erosion depths in Si films deposited on Al substrates by PVD, CVD and plasma spay methods were measured after exposure to As+ ions a DC implanter beam Ga+ with scanned FIB. Erosion are optical methods. Metallic contamination the RBS. surface textures examined SEM.
