Light emission from hydrogenated and unhydrogenated Si-nanocrystal/Si dioxide composites based on PECVD-grown Si-Rich Si oxide films
(Institute of Electrical and Electronics Engineers, 2006-12)
Hydrogenated and unhydrogenated Si-nanocrystal/Si dioxide (Si-nc/SiO2) composites were obtained from SiyO1-y (y=0.36, 0.42) thin films deposited by plasma-enhanced chemical vapor deposition. The unhydrogenated composites ...

Allometric growth of non-carcass components in crossed lambs
(Universidade Federal de Santa Maria, 2014-07-01)
Males and females, including purebred Santa Inês lamb (SI) and crosses between Santa Inês dams and Texel (TxSI), Ile de France (IFxSI) and Bergamasca (BxSI) sires were feedlot finished and slaughtered at 15, 25, 35 and ...
Microstructural characterization of as-cast Cr-Si alloys
(ELSEVIER SCIENCE INC, 2008)
This work presents results of microstructural characterization of as-cast Cr-Si alloys. The alloys were prepared by arc melting pure Cr (min. 99.996%) and Si (min. 99.998%) powder mixtures under argon atmosphere in a ...
Obtenção in situ do compósito alfa-SiAlON-SiC
(Associação Brasileira de Cerâmica, 2005-12-01)
O objetivo desse trabalho foi a preparação in situ do compósito alfa-SiAlON-SiC com desenvolvimento de solução sólida de nitreto de silício (SiAlON) durante a sinterização, utilizando o óxido misto de ítrio e terras raras ...

Controlled growth of extended arrays of CoSi2 hexagonal nanoplatelets buried in Si(001), Si(011) and Si(111) wafers
(Royal Society of Chemistry, 2015-01)
Because of their high electrical conductivity CoSi2 nanostructures are potential candidates for preparing ordered nano-arrays to be used as electrode interconnectors and contacts in microelectronic devices. We here describe ...
Growing Si Nanocrystals within a-Si Nanoclusters Embedded in a-SiO2: Evolution of Photoluminescence
(The Electrochemical Society, 2012-06)
We combine X-ray absorption, electron spin resonance and Raman spectroscopies, X-ray diffraction and photoluminescence (PL) techniques to determine the structure and luminescence mechanisms in Si nanoclusters (Si-ncls) ...
