In summary, an isotropic dielectric is a material where the dielectric constant is the same in all directions, which means all off diagonal elements in the matrix \chi are zero. This type of dielectric does not exist in nature, but can be created in a laboratory. ...
To improve the breakdown voltage of ceramic capacitors, coating a layer of glass glaze around the edges of the interface between the electrode and the dielectric surface can effectively improve the withstand voltage and high-temperature load performance of ceramic capacitors used in high-voltage circuit...
A method for detecting dielectric breakdown in the signal of cathodoluminescence in SEM is compared with both capacitive and secondary-emission methods. In the investigated samples of glass dielectrics, breakdowns of two types are found: surface and emission. The prospects for using cathodoluminescence ...
Surge arrester failure can result in short circuits in houses. In most of the situations, a fault occurs because of dielectric breakdown once the internal structure of the system damages. So the arrester cannot resist the applied voltage like lightning, normal system voltage, switching surge overvo...
The diameter of the nanopore was approximately 2 nm, and the nanopore was made by utilizing the dielectric breakdown of the membrane30, 31. When the Si probe approaches the membrane, an ssDNA is directed to the nanopore by the electric field near the nanopore. The process of immobilizing ...

When the vacuum degree deteriorates to 10-2-10-1 Pa, although the breakdown voltage does not decrease, the arc extinguishing chamber is no longer qualified. The vacuum degree measuring instrument adopts a new type of excitation coil and uses the magnetron...
The causes of electrical stress failure include electrostatic discharge (ESD), surface breakdown, dielectric failure, overvoltage, and surface trapping. ESD Extreme electrical stress causes ESD that results in catastrophic failure, permanent parameter variation, and hidden damage. This might occur because...
What are mica capacitors? Mica is a group of natural minerals. Silver mica capacitors are capacitors which use mica as the dielectric. There are two types of mica capacitors: clamped mica…
Answer: The breakdown voltage of a diode is the base opposite voltage applied to make the diode breakdown. This leads the diode conduct in the reverse direction. If a sufficient electric field is applied, all insulators become conveyors or conductors. On the off chance that the voltage applied...
