If dielectrics other than an oxide such as silicon dioxide (often referred to as oxide) are employed the device may be referred to as a metal–insulator–semiconductor FET (MISFET). Source: Internet
Further technology advances that use even thinner gate dielectrics have an additional leakage component because of current tunnelling through the extremely thin gate dielectric. Source: Internet
At the plasma frequency and above, dielectrics behave as ideal metals, with electron gas behavior. Source: Internet
For some dielectrics, such as many polymer films, the resulting voltage may be less than 1-2% of the original voltage. Source: Internet
In particular, at extremely large frequencies (above the plasma frequency ), metals become transparent to photons (such as X-rays ), and dielectrics show a frequency-dependent cutoff as well. Source: Internet
It is also used to produce other barium chemicals, notably barium carbonate which is used for the manufacture of LED glass for television and computer screens ( historically in cathode ray tubes); and for dielectrics. Source: Internet
