WebApr 13, 2024 · From this capacitive model, one observes that a dielectric layer with large ε d and small t d is desired to lower the required applied voltage. Another critical parameter for the selection of the dielectric material in our system is electric breakdown field strength, E BD = V max /t. A larger E BD means larger magnitudes of ΔV max and Δζ ... WebThe dielectric constant of a material, also called the permittivity of a material, represents the ability of a material to concentrate electrostatic lines of flux. In more practical terms, …
