Electrical breakdown and volt-ampere characteristics in water vapor in microgaps

EPL (Europhysics Letters), 2012
Although the physics for breakdown initiation in gases in generally well understood, the process of breakdown initiation in liquids is much less clear. A large number of experimental data on the breakdown in water revealed that the breakdown voltage in water is of the same magnitude as in the case of gases.

Electrogradient EMF and volt-ampere characteristics of inhomogeneous systems

Soviet Physics Journal, 1978
This paper studies the manifestation of electrogradient effects in the shape of the voltampere characteristics (VAC) of inhomogeneous conducting sandwich structures of the SSS and MSM types (S stands for n-type semiconductor, and M for metal) during the passage of a current perpendicular to the interfaces between the materials.

Subharmonic structure of the volt-ampere characteristics of superconducting tunnel junctions

Soviet Journal of Low Temperature Physics, 1975
Amplitude beats of the subharmonics have been observed in the dV / dI— V characteristics of Pb–PbOx–Pb junctions. The reduction of the temperature to 0.75 °K during the measurements provided the basis for assuming that the beats are caused by interference between a series of minima (eV=2Δn−δV) shifted along the V axis and an unshifted series of odd ...

Asymmetry of Volt-Ampere characteristics in poled polycrystalline Ferroelectrics-Semiconductors

Ferroelectrics, 1995
In poled polycrystalline ferroelectrics-semiconductors with intergranular potential barriers the voltampere characteristics are found out to be asymmetric, the current density along the polarization direction being smaller than that in the opposite direction. The degree of asymmetry increases with measuring field.

Test Set for Displaying the Volt-Ampere Characteristics of Tunnel Diodes

Review of Scientific Instruments, 1960
A test set is described which permits the display of the V-I (volt-ampere) characteristic of a tunnel diode on an oscilloscope. The circuit instabilities which usually exist when a negative resistance device is tested on a V-I curve tracer are suppressed in the unit described. The principles of design, construction, and operation are presented.
