Determination of Dielectric Constant

Introduction The dielectric constant of PCB material is important in determining the trace width required to produce a characteristic impedance of 50 ohms, or any other desired impedance. The most commonly used material, FR-4, has a dielectric constant that may vary widely between manufacturers or batches, and also varies over frequency. It is useful to have a method to determine the dielectric...

High dielectric constant oxides

The scaling of complementary metal oxide semiconductor (CMOS) transistors has led to the silicon dioxide layer used as a gate dielectric becoming so thin (1.4 nm) that its leakage current is too large. It is necessary to replace the SiO2 with a physically thicker layer of oxides of higher dielectric constant (κ) or ‘high K’ gate oxides such as hafnium oxide and hafnium silicate. Little was know...

Modelling the Dielectric Constant of Rice Grains

ABSTRACT. A new technique for the measurement of dielectric constant of materials, using a partially filled waveguide cell and a new mixture equation, has been developed which is first tested for teflon and then used to measure the dielectric constant of rice and air mixture in the frequency range of 2.6GHz to 3.9GHz. The values of dielectric constant of rice grain obtained using the mixture mo...

Dielectric constant of water in the interface.

We define the dielectric constant (susceptibility) that should enter the Maxwell boundary value problem when applied to microscopic dielectric interfaces polarized by external fields. The dielectric constant (susceptibility) of the interface is defined by exact linear-response equations involving correlations of statistically fluctuating interface polarization and the Coulomb interaction energy...
