Electrical Breakdown of Nanowires

Nano Letters, 2011
Instantaneous electrical breakdown measurements of GaN and Ag nanowires are performed by an in situ transmission electron microscopy method. Our results directly reveal the mechanism that typical thermally heated semiconductor nanowires break at the midpoint, while metallic nanowires breakdown near the two ends due to the stress induced by ...

Electrical Breakdown in Water Vapor

Physical Review E, 2011
In this paper investigations of the voltage required to break down water vapor are reported for the region around the Paschen minimum and to the left of it. In spite of numerous applications of discharges in biomedicine, and recent studies of discharges in water and vapor bubbles and discharges with liquid water electrodes, studies of the basic ...

Biased percolation and electrical breakdown

Semiconductor Science and Technology, 1997
To analyse the degradation of a thin-film conductor we have extended the biased percolation model to the case of electrical breakdown associated with a systematic decrease of the resistance. As relevant indicators of the degradation process we have chosen the damage pattern, the current and temperature distributions, the change of resistance, the ...

Electric Breakdown

Physics Today, 1950
Pure single crystals subjected to an intense electric field under carefully controlled conditions break down at characteristic minimum field strengths (about 10° volts per centimeter).

Electrical breakdown in gases

Digest of Literature on Dielectrics Volume 42 1978, 1978
The aim of this chapter is to gather information relevant to the electrical discharges and breakdown in insulating gases. References to the vast amount of literature on gas lasers, thermonuclear plasmas, magneto-hydrodynamics, high energy physics and many of the other related technical areas that make use of gas discharges are excluded from this ...

Electrical breakdown in gases

Digest of Literature on Dielectrics, Volume 41, 1977, 1977
The subject of electrical discharges in gases is a very general one which encompasses many other fields, such as plasma chemistry and laser processes, while it, in turn, makes use of results obtained in such allied areas as the physics of collisions. This lack of clearly defined boundaries creates inevitable difficulty for someone attempting to compile

Electric Breakdown in Ionic Crystals

Physical Review, 1949
The electric breakdown strength of ionic crystals at low and moderate temperatures is calculated on the basis of von Hippel's low energy criterion. Fr\"ohlich's method of calculation, modified to take account of the electronic polarizability of the ions, is employed.

Dipoles and electric breakdown

Applied Scientific Research, 1957
It is shown that breakdown of insulating or dielectric material may be caused either by polarizable particles or permanent dipoles. Induced dipoles as well as permanent dipoles may gather at a place of maximum stress and form a bridge. Bridges consisting of permanent dipoles may cause the gap between the valence energy band and the conduction energy ...

Electrical breakdown, electropermeabilization and electrofusion

2006
The considerable amount of activity in the field of electrofusion and electropermeabilization is very promising from the point of view of new insights into biomembranes and new technologies in the future for the production of new compounds and modification of cell systems for nutrition, energy production and the removal of waste products.
