Porous silicon nanocrystals in a silica aerogel matrix

Silicon nanoparticles of three types (oxide-terminated silicon nanospheres, micron-sized hydrogen-terminated porous silicon grains and micron-size oxide-terminated porous silicon grains) were incorporated into silica aerogels at the gel preparation stage. Samples with a wide range of concentrations were prepared, resulting in aerogels that were translucent (but weakly coloured) through to compl...

Optical Properties of Silicon Nanocrystals Embedded in SiO2 Matrix

From the view point of both science and technology, it would be interesting and useful to examine the optical properties of isolated silicon nanocrystals (nc-Si) embedded in SiO2 matrix. A good understanding to optical properties of the nc-Si is definitely important to both the quantum physics and the applications especially in optoelectronic and photonic devices. In this work, spectroscopic el...

XPS Studies of Silicon Nanoclusters/Nanocrystals Embedded in SiO2 Matrix

In this study, the analysis of the XPS Si 2p peaks shows the existence of the five chemical structures corresponding to the Si oxidation states Si n+ (n =0, 1, 2, 3, and 4) in Si-implanted SiO2 films, and the concentration of each oxidation states is determined quantitatively. The evolution of the five Si oxidation states as a function of thermal annealing is studied. On the other hand, Si 2p c...

Si Nanocrystals Embedded in a Silicon Oxynitride Matrix

We investigated the morphological and structural change in silicon nanostructures embedded in the silicon oxynitride matrix. The study has been carried out on thin films thermally annealed at high temperature, after deposition at 400°C by Electron Cyclotron Resonance Plasma Enhanced Chemical Vapour Deposition (ECR‐ PECVD), under different deposition parameters. Our stud...
