The dielectric strength of silicon dioxide, [math]SiO_2[/math] is about 10 MegaVolts/cm which works out to 1000 V/micrometer. Thin films are on the order of 0.1 micrometers and should therefore have a breakdown of about 100 V. This is rarely achie

Relative Permittivity - the Dielectric Constant

The dielectric constant - also called the relative permittivity indies how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum".. Relative permittivity can be expressed as ε r = ε / ε 0 (1)
