Relative Permittivity - the Dielectric Constant Common materials and their relative permittivity. The dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of ...

The dc electric-field dependence of the relative dielectric constant (E) in polar dielectrics is studied. The Landau-Ginzburg-Devonshire (LGD) theory and its approximate treatments in dealing with (E) are reviewed. It is found that the LGD theory works well in the case of a single polarizatio...
The concentration of defects was determined by the equation Ndefects = 2εε0VTFL/qL2, where q is the elementary charge, ε is the relative dielectric constant, ε0 is the vacuum permittivity, and L is the thickness of the perovskite films obtained from the cross-sectional SEM images ...
The dielectric constant (also known as relative permittivity) is a measure of a material’s ability to store electrical energy in an electric field. Written by Artem Oppermann Published on Feb. 10, 2023Image: Shutterstock / Built InWe define the dielectric constant as the ratio of the electric...
