Asymmetry of Volt-Ampere characteristics in poled polycrystalline Ferroelectrics-Semiconductors
Ferroelectrics, 1995In 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.

Research of volt-ampere characteristics testing method for photovoltaic cells
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015Volt-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 ...

Electrical breakdown and volt-ampere characteristics in water vapor in microgaps
EPL (Europhysics Letters), 2012Although 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.

Subharmonic structure of the volt-ampere characteristics of superconducting tunnel junctions
Soviet Journal of Low Temperature Physics, 1975Amplitude 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 ...

[Static volt-ampere characteristics of biologically active human skin currents].
Biofizika, 1980Results are presented of measuring static voltage characteristics of biologically active sites Xe-gy at various pressure of the measuring electrode on the skin. It has been shown that under other equal conditions conductivity of the active sites is 3 and more times higher than that of inactive sites in the whole range of the applied pressures.

Test Set for Displaying the Volt-Ampere Characteristics of Tunnel Diodes
Review of Scientific Instruments, 1960A 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.
