WebApr 13, 2024 · Although SiO 2 is not considered a high-k dielectric (ε SiO2 ∼4 vs ε HfO2 ∼20), it is overall a high performance dielectric due to its extremely high E BD ∼890MV m −1, which is much higher than hafnia's E BD ∼50MV m −1. This allows for a large range of accessible ζ and, critically, the ability to change the sign of surface ζ.
Capacitance is the capability of a material object or device to store electric charge. It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities. Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance. An object that can be electrically charged exhibits self ca…
