Current limiting and negative differential resistance in indium oxide based ceramics [PDF]

open access: yes, 2009
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.

Thermal behaviour analysis in a porcelain-housed ZnO surge arrester by computer simulations and thermography

open access: yesHigh Voltage, 2019
In this article, an analysis of heat transfer in a porcelain-housed ZnO surge arrester is presented. Due to the fact that ZnO-based surge arresters are key components for protection and reliability of electrical systems, it is necessary to seek ...

Microstructural and nonohmic properties of ZnO.Pr6O11 CoO polycrystalline system

open access: yesMaterials Research, 2010
The microstructure and electrical properties of varistors composed of (95-x) ZnO + x Pr6O11 + 5 CoO (ZPC), (x = 0.1, 0.5 and 1.0) and sintered at 1300 and 1350 °C, were investigated. According to X-ray diffraction, several phases (ZnO, Pr2O3 and Pr2CoO4)

Mathematical model predicting the heat and power dissipated in an electro-conductive contact in a hybrid woven fabric [PDF]

open access: yes, 2020
Electro-conductive (EC) yarns can be woven into a hybrid fabric to enable electrical current to flow through the fabric from one component A to another component B. These hybrid fabrics form the bases of woven e-textiles.

A supercapacitor based enhancement technique for stand-alone surge protection circuits [PDF]

open access: yes, 2013
With the International Technology Roadmap for Semiconductors predicting below-25nm feature-size VLSIs, powered by DC power supplies of less than 1V, protection against transients has become mandatory for modern electronic systems.

Non-Linear I-V Characteristics of Double Schottky Barriers and Polycrystalline Semiconductors

open access: yes, 1992
An attempt to determine theoretically the highly non-linear current-voltage (I-V) characteristics of polycrystalline semiconductors, such as ZnO-based varistors, is made from the electrical properties of individual grain boundaries under dc bias.

Random manifolds in non-linear resistor networks: Applications to varistors and superconductors

open access: yes, 2001
We show that current localization in polycrystalline varistors occurs on paths which are, usually, in the universality class of the directed polymer in a random medium.
