X-ray photoelectron spectroscopy (XPS) and medium energy ion scattering (MEIS) are used to determine chemical bonding and composition of ultra-thin films of mixed yttrium, silicon, and oxygen, formed by oxidation of metal on clean and pre-treated silicon. XPS and MEIS analyses indicate that oxidation of yttrium on bare silicon results in a fully oxidized film with a significant fraction of Y-O-...

At room temperature, 300 K, silicon carbide film was formed using monomethylsilane gas on the reactive surface prepared using argon plasma. Entire process was performed at reduced pressure of 10 Pa in the argon plasma etcher, without a substrate transfer operation. By this process, the several-nanometer-thick amorphous thin film containing silicon-carbon bonds was obtained on various substrates...

Objective(s): Due to nanocomposites antimicrobial properties, one of the most extensive usages of nano-products is in packing industry. Thus, the production of packages with nanotechnology can effectively prevent against a variety of microorganisms. In this study, the silicon dioxide nanoparticles the poly (lactic acid) PLA films on antimicrobial and permeability was investigated. Methods...

Post-crystallization heat-treatment of metal-induced laterally crystallized polycrystalline silicon thin film using YAG solid-state laser is characterized. It is found that both the material quality and the TFT performance are related to the laser-treatment condition. The amorphous silicon fraction remaining in the polycrystalline thin film can be reduced and the performance of the thin-film tr...

The solidification of two-dimensional liquid silicon confined to a slit nanopore has been studied using molecular dynamics simulations. The results clearly show that the system undergoes an obvious transition from liquid to multilayer hexagonal film with the decrease of temperature, accompanied by dramatic change in potential energy, atomic volume, coordination number and lateral radial distrib...

The edible mushroom Agrocybe chaxingu was stored in packages with or without silicon gum film windows in three different modified atmosphere systems (5% O2, with 5%, 10% and 15% CO2) at a temperature of 3± 1 ◦C. The results showed that there were significant differences between the packages with and without the silicon gum film windows on O2, CO2, and ethylene concentrations, respiration rate, ...

Mobility in advanced MOSFETs with strained ultra-thin silicon body is investigated. We use a two-band k·p model to describe the subband structure in strained silicon thin films. The model provides the dependence of the conductivity effective mass on strain and film thickness. The conductivity mass decreases along tensile stess in [110] direction applied to a (001) silicon film. This conductivit...

This work was an experimental study of the aluminum-induced crystallization (AIC) of amorphous silicon (a-Si) for the fabrication of polycrystalline silicon film. The a-Si film was deposited on silicon wafer by low pressure chemical vapor deposition (LPCVD) technique. Aluminum was sputtered on to the a-Si film at different thicknesses. The samples were annealed for 3 h at different temperatures...

We demonstrated a novel, simple, and low-cost method to fabricate silicon nanowire (SiNW) arrays and silicon nanohole (SiNH) arrays based on thin silver (Ag) film dewetting process combined with metal-assisted chemical etching. Ag mesh with holes and semispherical Ag nanoparticles can be prepared by simple thermal annealing of Ag thin film on a silicon substrate. Both the diameter and the distr...

In our experiment, it was observed that silicon nanocrystal rapidly grows with irradiation of electron beam on amorphous silicon film prepared by pulsed laser deposition, and shape of silicon nanocrystal is usually sphere in smaller nanoscale with less exposure time under electron beam, in which the quantum dots are prepared in nanoscale near 3 nm. In the electron interaction process, it was in...
