Dielectric breakdown characteristics of alumina

2010 10th IEEE International Conference on Solid Dielectrics, 2010
The AC 50 Hz sine dielectric breakdown of alumina ceramics versus thickness (0.127 to 2.54 mm) and purity (92%, 96% and 99.5%) was investigated. The results have shown that the dielectric strength decreases with the thickness and increases with the purity.

Breakdown characteristics of askarels

1971 EIC 10th Electrical Insulation Conference, 1971
Examination of the results plotted in the graphs demonstrates that they grow whilst resident on the electrode surface. Probably tions i.e. reliability against voltage, -ln R against voltage, In (-ln R) against voltage are all continuous except at a voltage of 9 kV.

Electrical Breakdown Characteristics of Soil

IEEE Transactions on Nuclear Science, 1982
The pulsed electrical breakdown characteristics of soil between a hemispherical and a planar electrode have been measured in meter-size geometries for three soil types with water contents from 1 to 7% by volume. The threshold electric field for breakdown is a function of the soil type and the water content, varying from about 1 to 2 MV/m locally near ...

Breakdown characteristics of gallium arsenide

IEEE Electron Device Letters, 1981
This paper presents a comparison of the experimentally measured breakdown characteristics of high-purity gallium arsenide epitaxial layers with the theoretical calculations reported in the literature. The experimental data has been obtained by forming gold Schottky barrier diodes on material grown by using two different liquid phase epitaxial growth ...

Voltage breakdown characteristics of microwave antennas

IRE International Convention Record, 1959
At low pressures, antennas are susceptible to voltage breakdown. In the case of missiles, for example, there are indications that very low power is sufficient to initiate and maintain breakdown. Since it is essential that the system performance is not interrupted for high-altitude operation, an experimental investigation has been made to study the ...

Fractal characteristics of dielectric breakdown

Proceedings of IEEE Conference on Electrical Insulation and Dielectric Phenomena - (CEIDP'94), 2002
Wiessman and Zeller (WZ, 1986) applied a simple two-dimensional stochastic model in order to apply it to the stepwise propagation of those damage structures known as electrical trees. These branching structures propagate by the repeated extension of the individual tips of damage channels and they have fractal characteristics similar to those observed ...

Breakdown Characteristics of Porous Metals

Japanese Journal of Applied Physics, 2004
We have investigated the breakdown characteristics of porous metals as discharge electrodes, for applications to multichannel arc gaps. We examined a single-needle/plane gap as a nonuniform electric field gap and a sphere/plane gap as a uniform one using a mirror-finished brass plate and a porous metal as plane electrodes.

Breakdown characteristics of interconnect dielectrics

2005 IEEE International Reliability Physics Symposium, 2005. Proceedings. 43rd Annual., 2005
The shrinking of line-to-line spacing in interconnect systems for advanced IC technology and the use of new lower dielectric constant materials create the need for tools to evaluate the interconnect dielectric reliability. A multi-temperature, dual ramp-rate voltage-ramp to breakdown methodology is presented and used here to extract important ...

Self-healing breakdown characteristics of polyimide thin films-effect of ambient gas on breakdown characteristics

IEEE 1997 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2002
We have been studying the breakdown characteristics of polyimide (PI) thin films to try and take advantage of self-healing breakdown. This paper focuses on the effect of ambient gas (SF/sub 6/, N/sub 2/, O/sub 2/ and dry air) on breakdown characteristics of PI thin films.

AC breakdown characteristics of epoxy nanocomposites

IEEE Transactions on Dielectrics and Electrical Insulation, 2011
Experiments were conducted to measure the ac breakdown strength of epoxy alumina nanocomposites with different filler loadings of 0.1, 1 and 5 wt%. The experiments were performed as per the ASTM D 149 standard on samples of thickness 0.5 mm, 1 mm and 3 mm in order to study the effect of thickness on the ac breakdown strength of epoxy nanocomposites.
