Applications Why Do We Need High-x Materials

Dielectric materials are insulators, and when they are placed between two plates with area A at a distance t apart, equal to the dielectric thickness, a parallel plate capacitor is fabricated. Its capacitance (C) increases with decreasing distance t as well as increasing permittivity of the material applied, according to C=e oA t. 

A DRAM is a volatile computer memory consisting of two components a transistor functioning as an access switch and a capacitor. Every bit of information is stored as a charge on such a capacitor. Because the charge leal s away, the memory is volatile and needs to be refreshed frequently. 

A TFT (thin film transistor) is one of the key components in TFT displays, which contain one transistor for each subpixel. This transistor is a field-effect
