Permittivity is a measure of a material's ability to store electrical energy in an electric field. In non-ferroelectric materials, permittivity is a measure of the material's ability to polarize in response to an electric field.
Yes, the permittivity of non-ferroelectric materials is dependent on temperature. As the temperature increases, the permittivity of the material generally decreases.
The change in permittivity with temperature is due to the thermal expansion and movement of atoms within the material. As the temperature increases, the atoms vibrate more and are less able to align in response to an electric field, resulting in a decrease in permittivity.
No, the relationship between permittivity and temperature can vary for different non-ferroelectric materials. Factors such as the type of material, its crystal structure, and the strength of intermolecular forces can all affect the temperature dependence of permittivity.
Yes, the temperature dependence of permittivity can be controlled through various methods such as doping the material with impurities or introducing defects in the crystal structure. This allows for the possibility of designing materials with specific permittivity-temperature relationships for different applications.
