Thermochemical property estimation of hydrogenated silicon clusters.

Thermochemistry of Silicon-Hydrogen Compounds Generalized from Quantum Chemical Calculations

Particulate contamination formed by homogeneous clustering reactions of silicon hydrides within silicon chemical vapor deposition processes is an important source of yield loss during semiconductor processing. On the other hand, intentional synthesis of silicon nanoparticles may be of great interest because of the unique optical and electronic properties of nanostructured silicon. Kinetic model...

Numerical Modeling of Non-equilibrium Plasma Discharge of Hydrogenated Silicon Nitride (SiH4/NH3/H2)

In this work, we model a radiofrequency discharge of hydrogenated silicon nitride in a capacitive coupled plasma reactor using Maxwellian and non-Maxwellian electron energy distribution function. The purpose is to investigate whether there is a real advantage and a significant contribution using non-Maxwellian electron energy distribution function rather than Maxwellian one for determining the ...

Electronic and superconducting properties of silicon and carbon clathrates

We review the electronic properties of pure and doped silicon and carbon clathrates. Using accurate quasiparticle calculations within the GWapproximation, we show that undoped clathrates are 1.8 eV band gap semiconducting compounds. Further, the effect of doping by elements more electronegative than Si is shown to lead to p-type doped semiconductors with a 2.3–2.5 eV band gap in the visible ene...

Studies of picosecond carrier dynamics in polysilane alloys: Evidence for geminate recombination in small hydrogenated amorphous silicon clusters

LABORATORY STUDIES ON THE INFRARED ABSORPTIONS OF HYDROGENATED CARBON-SILICON CLUSTERS: DIRECTING THE IDENTIFICATION OF ORGANOMETALLIC SiCHx SPECIES TOWARD IRC +10216

Silicon-bearing species of the molecular formula SiCHx (x 1⁄4 1 6) are plausible candidates for organometallic molecules that might be present in the circumstellar envelope of IRC +10216. Combining matrix-isolation laboratory experiments with computed vibrational spectra of these molecules, we have observed several fundamentals of the new silicon-containing radicals SiCH3 and SiCH5, in addition...
