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.

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.

Research of volt-ampere characteristics testing method for photovoltaic cells

The 27th Chinese Control and Decision Conference (2015 CCDC), 2015
Volt-ampere characteristic(I-V) curve is one of the most important characteristics of solar arrays, and is an indispensable reference for field performance testing and designing of concentrating photovoltaic power generation system. However, customers can only get the curve under standard condition from manufacturers, but the actual operating ...

Volume Recombination, Constriction, and Volt-Ampere Characteristics of the Positive Column

Physical Review, 1962
Positive characteristics have been found for diffuse, striationfree, 1-20 ma dc, positive columns in 150-mm Xe, Kr, or Ar, with 0.1% ${\mathrm{N}}_{2}$ in 10-cm tubes. With Xe+${\mathrm{N}}_{2}$, a continuous spectrum is emitted; with other rare gases selections of ${\mathrm{N}}_{2}$ bands.

The volt-ampere characteristics of the leakage and emission current of sandwich cathodes

Czechoslovak Journal of Physics, 1966
The study of the properties of a metal-dielectric-metal system in a strong electric field has so far led to heterogeneous results. Their agreement with theory is unsatisfactory or lacking entirely. The theoretical conceptions are based on the assumption of the field emission of electrons from the surface of metals to the conduction band of the ...

Determination of Ion Temperature from the Volt–Ampere Characteristics of Electrolytes

Journal of Engineering Physics and Thermophysics, 2017
The author presents experimental volt–ampere characteristics measured in various media. From them, the density of ions and their temperature have been determined. An estimating formula has been derived for the thickness of a space-charge layer. It has been proposed in this work that the Fermi distribution function be used to calculate the thickness of ...
