The calculated values of trap densities (Ht) were 7.73×1011 cm3 and 5.34×1011 cm3 for p-SPT device and n-SPT device respectively. Similarly p-SPT device shows higher real part of dielectric constant (ε′) and AC conductivity (σac) 15 times and 85 times respectively than that of n-...
dielectric constant of the filter material. Relatively small filters can be fashioned from relatively high dielectric constant materials, whereas filter size must be increased as the dielectric constant is decreased. While very high dielectric constant materials might be considered desirable for ...

SOLUTION: The porous silica film has a relative dielectric constant of less than 2.5 and is obtained by baking a film of a composition containing polyalkylsilazan and polyacrylic acid ester or polymetacrylic acid ester.AOKI TOMOKO
The invention also discloses a preparation method of the composite film. The fluorine-containing polymer-based dielectric composite film is a dielectric composite film which has the advantages of high dielectric constant, high compressive strength, low dielectric loss and excellent elongation and ...
The dielectric constant of materials usually used in electronics is shown in Table 5. Table 5. Dielectric constants of materials used in electronics. Hereinafter, different biobased and/or biodegradable materials that exhibit dielectric properties and are good candidates for formulating dielectric inks ...
In the interfacial studies of hydrogels, electron polarization (EP) effect is the challenge that must be faced because the EP effect produces a huge dielectric constant that can overwhelm the inherent signal of the hydrogels. The EP effect was avoided by measuring ice-hydrogels instead of water-...
