Abstract:
Trace metal contamination of the air-soil-tree system was examined in southern Quebec, where acid deposition and tree dieback have been recorded in high elevation forests. Mn pollution was emphasized due to its large emission from gasoline combustion in Canada. Airborne Cu, Mn, V, and Zn showed higher concentrations than those reported for other remote locations. Significant fluctuation in Mn concentrations during the winter-spring season was explored by air mass back trajectory analysis. The study suggested that high Mn concentrations resulted from the atmospheric long-range transport from Ca

The scales formed on A24 and SB450 were triple layer consisting of Fe2O3, Fe3O4, and FeO from the outer to the inner lay

In this study, ZrN films were deposited on AISI D2 steel using a hollow cathode discharge ion-plating (HCD-IP) technique. Heating environment, including air, Ar/H2, and Zr and Ti getters were discussed with thermodynamic and kinetic analysis. The specimens were heat-treated at 700℃ for 1 hour under optimal atmosphere to reduce oxidation of the thin films. The microstructure, resistivity and packing factor of the heat-treated ZrN thin films were not significantly changed. Ho

But gate leakage current becomes higher when shrinking of the gate length and gate dielectric thickness. Using high dielectric constant material for gate dielectric instead of SiO2 will solve the problem of the gate dielectric thickness. The oxide-based thin film transistors have good electrical properties and high transparency. Amorphous indium gallium zinc oxide (a-IGZO) has advantages of relatively high electron mobility and good chem

We must use low-temperature process of PECVD to deposit silicon dioxide. With the area of display increase day by day, we have to design larger vacuum chamber and associated pumping system but the cost of equipment will increase.

The films were processed by changing work pressure, process time, and RF power to get appropriate properties of films. After deposition, the IGZO samples were treated in various atmosphere plasma and vacuum annealing. After the atmosphere plasma and vacuum annealing treatment, the IGZO properties could further improve such as transmittance and resistivity. According to the experiment results, better properties of IGZO films were obtained at lower work pressure. When the d
