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...
متن کاملOptical 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...
متن کاملXPS 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...
متن کاملStructural, electrical and photovoltaic characterization of Si nanocrystals embedded SiC matrix and Si nanocrystals/c-Si heterojunction devices
Thin films of Si nanocrystals (Si NCs) embedded in a silicon carbide (SiC) matrix (Si-NC:SiC) were prepared by alternating deposition of Si-rich silicon carbide (Si1 xCx) and near-stoichiometric SiC mutilayers (Si1 xCx/SiC) using magnetron cosputtering followed by a post-deposition anneal. Transmission electron microscopy and Raman spectroscopy revealed that the Si NCs were clearly established,...
متن کاملEnergy Transfer from Silicon Nanocrystals to Er Ions Embedded in Silicon Oxide Matrix
Silicon (Si) based light emitting devices have drawn much attention for the integration of electronic and photonics. Si nanostructures (amorphous clusters or crystals) have been recognized as good candidates for effective light emitting devices (Bulutay, 2007; Seino et al., 2009; Takagahara & Takeda, 2007; Wolkin et al., 1999). However, photons emitted by Si nanostructures can be reabsorbed by ...
