SEM Contrast of Semi-insulating Compound Materials

Semi-insulating Liquids

Charge separation near a liquid/solid interface is explored by the electrohydrodynamic pumping of Freon TF, transformer oil, and silicone oil using high voltage traveling waves. Liquid head displacement measurements show strong dependencies on peak voltage amplitude (1.0-2.5 kV), frequency (0.1-20 Hz), liquid viscosity (0.5-20 cS), and liquid conductivity to 10-9 0-lm-l ). Reverse pumping, oppo...

Structure of Semi-Insulating Polycrystalline Silicon (SIPOS)

Semi-Insulating Polycrystalline Silicon (SIPOS) films were deposited on Si02/Si, Si, and sapphire substrates by the chemical vapor deposition of silane and nitroiJs oxide at atmospheric and low pressures. X-ray diffraction was used to identify the phases present, and to study structural properties like grain size and strain as a function of the flow rate ratio, ~, = [N20]/[SiH4].oBoth APCVD and...

Radon permeability of insulating building materials

The common presence of the radioactive nuclides in the environment cause that the whole population are exposed to radiation. The dose that is annually received by Polish population from natural sources of radiation is about 2.4 mSv per year [1]. According to the UNSCEAR 2000 Report [2], radon is the greatest contributor of exposure to natural radiation for humans. Soil and the rocks on which th...
