Question

Effect of high k dielectric on current

Answer 1

Where κ and t are the dielectric constant and physical thickness of high-κ dielectrics. In this section, effect of tunneling current for various high-k dielectric materials have been studied. This also signify the effect of effective mass on performance of various high-k dielectric materials.

Answer 2

The termhigh-κ dielectricrefers to a material with a highdielectric constantκ (as compared tosilicon dioxide). High-κ dielectrics are used insemiconductor manufacturingprocesses where they are usually used to replace a silicon dioxidegate dielectricor another dielectric layer of a device. The implementation of high-κ gate dielectrics is one of several strategies developed to allow further miniaturization of microelectroniccomponents, colloquially referred to as extendingMoore's Law.
