Silicon-Based Optoelectronics: Progress and Challenges
Silicon-Based Optoelectronics Progress Challenges
2010/4/16
We review the status of silicon-based optoelectronics with emphasis on light emitting diodes. Erbium-doped Si, por-Si and silicon-based superlattices and nanostructures are discussed. The origin behin...
Effect of Ionizing Radiation on the Silicon IMPATT Diode Characteristics
Ionizing Radiation Silicon IMPATT Diode Characteristics
2010/4/15
We investigated the effect of 60Co g-irradiation (doses from 102 to 2 \times 106 Gy), both without and with heat annealing, on silicon IMPATT diode parameters. It is shown that such treatments improve...
Influence of Thermal Conductive Material on the Activation Energy of Amorphous Silicon Thin Films
Thermal Conductive Material Activation Energy
2010/4/19
The activation energy of amorphous silicon thin films are usually measured by placing the thin film sample on a heating surface and monitoring the change in the dark conductivity as a function of temp...

Preparation and Characterization of Montmorillonites Pillared by Cationic Silicon Species
Cationic silicon complexes Intercalation Microporosity Montmorillonite Oligosilsesquioxanes Pillared clays Thermal stability
2011/12/28
The hydrolysis of 2-(2-trichlorosilylethyl)pyridine (TCSEP) or 3-aminopropyltrimethoxysilane (APTMS) yields a complex mixture of oligomers, the composition of which is a function of time. 29Si NMR mea...
Influence of Silicon and Phosphorus on Structural and Magnetic Properties of Synthetic Goethite and Related Oxides
Electron diffraction Ferrihydrite Goethite Mossbauer spectroscopy Phosphorus Silicon X-ray powder diffraction
2012/1/9
A series of synthetic goethites containing varying amounts of Si and P dopants were characterized by X-ray powder diffraction, electron diffraction, microbeam electron diffraction, and M鰏sbauer spectr...
Tris(Acetylacetonato)Silicon(IV) Binding to Montmorillonite and Hydrolysis to Interlayer Silicic Acid
Hydrolysis Montmorillonite Pillared interlayer complex Si(acac)3+ Silicic acid
2012/2/2
The reactions of the tris(acetylacetonato)silicone(IV) cation (Si(acac)3+) with Na+-, Mg2+-, and Co2+-exchange forms of hectorite and montmorillonite have been investigated to understand better the fo...
Effects of Substitution of Germanium for Silicon in Imogolite
Germanium Imogolite Infrared spectroscopy Ionic substitution Synthesis
2012/2/7
Imogolites in which a part or all of Si was substituted with Ge were synthesized from solutions containing aluminum ion and silicic and/or germanic acid. The products were similar to natural imogolite...
Clay Mineral Stability as Related to Activities of Aluminium, Silicon, and Magnesium in Matrix Solution of Montmorillonite-Containing Soils
Clay Mineral Stability Aluminium Silicon Magnesium Montmorillonite-Containing Soils
2012/2/13
The influence of geomorphological site characteristics on soil clay mineral stability of montmorillonite-containing horizons of a southern Wisconsin soil catena was interpreted in terms of the solute ...
