Abstract: We study heavy ion irradiation effects on capacitors with the structure of a Floating Gate Flash cell. We demonstrate that the modifications of the capacitors electrical characteristics observed after irradiation depend on the physical position of the defects produced by ions into the dielectric.
In particular, we focus our attention on the leakage current produced by ion irradiation. We demonstrate that SiO 2 capacitors feature a leakage current higher than that observed in capacitors with an Oxide-Nitride-Oxide (ONO) stack as dielectric.
The self-discharge characteristic is particularly relevant when a supercapacitor is used for a long-term energy storage device in a wireless sensor system. In the present study, Maxwell supercapacitors were evaluated to determine the effect of TID irradiation on the capacitance during the irradiation process. The experiments on these supercapacitors were carried out to investigate this effect.
We demonstrate that SiO 2 capacitors feature a leakage current higher than that observed in capacitors with an Oxide-Nitride-Oxide (ONO) stack as dielectric. Finally, we investigate the behavior in time of the leakage produced by ions. Published in: IEEE Transactions on Nuclear Science ( Volume: 56 , Issue: 4 , August 2009 )
Few researchers have investigated the effects of high radiation on the electrical properties of supercapacitors. Their tolerance to radiation is a fundamental parameter in providing a sufficient and predictable operational life span for supercapacitors in nuclear decommissioning environments.
Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance which …

Los capacitores polarizados siempre tendrán algún tipo de indicador para la identificación de polaridad. Esto es importante, porque una conexión con la polarización incorrecta puede ser peligrosa.
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure (PageIndex{1}).
