Dielectric breakdown characteristics of alumina
2010 10th IEEE International Conference on Solid Dielectrics, 2010The 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.

Electrical Breakdown Characteristics of Soil
IEEE Transactions on Nuclear Science, 1982The 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 ...

Fractal characteristics of dielectric breakdown
Proceedings of IEEE Conference on Electrical Insulation and Dielectric Phenomena - (CEIDP'94), 2002Wiessman 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 gallium arsenide
IEEE Electron Device Letters, 1981This 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 ...

A study on the breakdown characteristics of the fluorocarbon
Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 2002In this paper, we investigated physical properties and electrical characteristics of the fluorocarbon used as coolants for large power gas-insulated transformers. Volume resistivity of the fluorocarbon is /spl rho/=1.87/spl times/10/sup 15/ [/spl Omega//spl middot/cm] at 1 atm, 27/spl deg/C.

Breakdown characteristics of interconnect dielectrics
2005 IEEE International Reliability Physics Symposium, 2005. Proceedings. 43rd Annual., 2005The 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 ...

Breakdown Characteristics of Porous Metals
Japanese Journal of Applied Physics, 2004We 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.

Characteristics of gas breakdown in hollow-core fibers
SPIE Proceedings, 2008We succeeded in obtaining gas discharge in 250-, 150-, and 50-mum inner-diameter (i.d.) hollow-core fibers (HCFs) by using longitudinal direct current excitation. Stable glow discharges of at least several minutes were observed for these HCFs. A flash glow was also observed for an HCF with an i.d. of ~20 mum. Breakdown of helium and argon gases in a 26.

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.

The Characteristics of Systems Breakdown
2016This chapter leverages the conceptual framework for how systems form to explain the many ways systems break down. These ways are organized into major methods, from violent destruction to intentional retirement, and specific breakdown mechanisms within each method.
