WebNov 10, 2024 · According to Wikipedia, permittivity is the ability to resist external electric field. This means a substance with high permittivity requires high external electric field to polarize. On the other hand, susceptibility is defined as the ability to polarize. So a substance with higher susceptibility should polarize easily.
WebThe term high-κ dielectricrefers to a material with a high dielectric constant(κ, kappa), as compared to silicon dioxide. High-κ dielectrics are used in semiconductor manufacturingprocesses where they are usually used to replace a silicon dioxide gate dielectricor another dielectric layer of a device.
