    Notes: In the present study, the flow structure inside the refrigerating compartment of a scaleddowndisplay cooler model was investigated experimentally using the particle image velocimetry(PIV) method, which is a reliable velocity field measurement technique. In addition, we also carriedout flow visualization and computer simulations regarding the movements of thermo-fluid inside adisplay cooler. As a result, the velocity field measurement shows a large scale vortical flowstructure inside the refrigerating compartment due to the entrained flow, thus penetrating a baseplate through the open inlet gap

    Origin of saturated light-induced defect density in hydrogenated amorphous silicon (1993)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The saturation of light-induced defect density in hydrogenated amorphous silicon (a-Si:H) has been studied as a function of various material parameters, such as initial defect density Ninit, Urbach energy Eu, hydrogen content cH, hydrogenated void fraction R, and deposition-induced annealable defect density ΔNann. These parameters were varied by depositing samples at various substrate temperatures or by postgrowth anneals of samples grown at low substrate temperatures. It is found that total defect density of saturated light-soaked state Nsat is well correlated with the Ninit, Eu, cH, R, and ΔNann in the as-grown states but no correlations between Nsat and parameters other than the Ninit, Eu, and ΔNann in the annealed states are found. It is also observed that annealing before light soaking reduces the Nsat substantially. In particular, it is found that the value of Nsat from the fully annealed state is much lower than that from the as-grown state with similar Ninit and Eu. A possible parameter that plays a primary role in the saturation of light-induced defects is discussed.

    Annealing effects on electron drift mobility in hydrogenated amorphous silicon (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 57 (1985), S. 4808-4810

    Topics: Physics
    Notes: Annealing effects on electron drift mobility are investigated using time-of-flight photocurrent measurements in hydrogenated amorphous silicon. It is found that at room temperature the electron drift mobility and dispersion parameters decrease as annealing temperature is increased, but mobility activation energy remains unchanged by annealing treatments. These results can be explained by the broadening of exponential band tail due to the annealing process.

    Notes: Undoped hydrogenated amorphous silicon films have been grown in multilayers with alternating substrate temperature between optimal and nonoptimal temperature for device-quality films. Compared to the single layer films grown at optimal substrate temperature, the multilayer films show improved stability in the light-induced state. Under intense light illumination of 3 W/cm2, the steady-state defect density of the layered film reaches a saturation of 2×1016 cm−3, while the single layer film saturates at 6×1016 cm−3. It is found that in the completely degraded state, the photoconductivity in the multilayer film is also improved by a factor of 3 compared to the single layer film. © 1996 American Institute of Physics.

    Saturation behavior of the defect density in hydrogenated amorphous silicon by continuous and pulsed light illumination (1995)
    Woodbury, NY : American Institute of Physics (AIP)

    ISSN: 1077-3118

    Topics: Physics
    Notes: Measurements of the saturated defect density in hydrogenated amorphous silicon by continuous and pulsed light illumination are reported. It is observed that the saturation value of the defect density by pulsed light illumination is about one order of magnitude higher than by continuous light illumination in device quality films. It has been suggested that this result would be due to the difference in the light-induced defect annealing rate between two cases, in which it is found that the light-induced annealing rate by pulsed light is lower than by continuous light with a similar intensity. © 1995 American Institute of Physics.

    Topics: Physics
    Notes: We have studied the annealing behaviors of deposition and light induced recombination centers, as measured by steady-state photoconductivity, in undoped hydrogenated amorphous silicon. It was found that both annealing activation energies are identical, and of 1.1 eV. In addition, the annealing activation energies of 1.1 and 1.7 eV were found for dark conductivity recoveries in the deposition and light induced defect annealing, respectively. The results are discussed on the basis of the existing models for recombination centers.

    Simulation of the oil spill processes in the Sea of Japan with regional ocean circulation model (1999)

    Notes: Abstract: A simulation of the movement of spilled oil after the incident of the Russian tanker Nakhodka in the Sea of Japan, in January 1997, was performed by a particle tracking model incorporating advection by currents, random diffusion, the buoyancy effect, the parameterization of oil evaporation, biodegradation, and beaching. The currents advecting spilled oil were defined by surface wind drift superposed on the three-dimensional ocean currents obtained by the Geophysical Fluid Dynamics Laboratory modular ocean model (GFDL MOM), which was forced by the climatological monthly mean meteorological data, or by the European Center for Medium Range Weather Forecasts (ECMWF) daily meteorological data, and assimilated sea surface topography detected by satellite altimeter. A number of experiments with different parameters and situations showed that the wide geographical spread of oil observed is not explained by wind drift alone, and that including the simulated climatological currents gives better results. The combination of surface wind drift and daily ocean currents shows the best agreement between the model and observations except in some coastal areas. The daily meteorological effect on the ocean circulation model results in a stronger variability of currents that closely simulates some features of the nonlinear large-scale horizontal turbulent diffusion of oil. The effect of different parameterizations for the size distribution of model oil particles is discussed.

    Notes: Abstract By using a rectangular basin of uniform depth with inflow and outflow openings, the circulation in the Japan Sea is investigated numerically. Heat flux through the sea surface is determined from the annual mean atmospheric conditions for the Japan Sea, but no wind stress is considered. In the transient state, the warm water supplied through an inflow opening travels cyclonically along the coast as a density-driven boundary current in a rotating system. In the quasi-steady state, the warm water flows northward as a western boundary current which corresponds to the East Korean Warm Current and gradually separates from the coast as it flows northward. No strong boundary current corresponding to the nearshore branch of the Tsushima Current exists. Under annual mean atmospheric conditions, formation of the deep water characteristic of the Japan Sea and of the thermal front corresponding to the Polar Front do not take place.

    Notes: Abstract Seasonal variations in the circulation in the Japan Sea are investigated numerically by using a model basin of uniform depth with three openings, one inflow opening corresponding to the Tsushima Straits and two outflow openings corresponding to the Tsugaru- and Sôya Straits. From winter to spring, warm water supplied through the inflow opening flows northward along the Korean coast as a western boundary current corresponding to the East Korean Warm Current. From summer to autumn, the warm water splits into two branches; one flows northward along the Korean coast as from winter to spring and the other flows along the Japanese coast as a density-driven boundary current due to the large density difference between the inflowing warm and low salinity water and the interior water which was cooled during winter. The lack of a boundary current along the Japanese coast from winter to spring results in a large discrepancy between calculated and observed salinity field distributions. Therefore, the nearshore branch of the Tsushima Current can not be explained only as a density-driven boundary current. The seasonal variation of atmospheric conditions plays an important role in the formation of the Proper Water and the Polar Front in the Japan Sea.

    Notes: Abstract By using a two-dimensional barotropic model on aβ-plane, the effect of the bottom topography on the path of the Tsushima Current is investigated. The rectangular model ocean with continental slopes has two openings: one is located at the southern boundary and the other at the eastern boundary. In a steady state, most of the water supplied into the model ocean through the inflow opening, flows along the continental slope with the coast to the right. Continental shelf waves play an important role in the process of adjustment to a steady state. It is suggested that the nearshore branch of the Tsushima Current might be largely topographically controlled.
