An increase in the dielectric constant (800 ± 15; 100 ≤ f ≤ 104 Hz) of PVDF without a coresponding increase in the dielectric loss is reported. This is realized by preparing sandwich structures composed of CNF/PVDF composite layers and a pure PVDF interlayer. The influence...
where ε′ is a constant of proportionality defined as the relative permittivity (dielectric constant) of the material between the electrodes, ε0 is a constant known as the permittivity of free space (1/3671×10−9 Farads m−1), A is the area of the electrodes (m2), and d is the...
The size-dependent dielectric constant from ε(a) is now (8.38)ε(a)=1+(ℏωp/Eg)2((E+−E−)/Eg)2=1+εB−11+(ΔE/Eg)2. Taking the parameters for Si, εB=12, Eg=4 eV, and filling the energy bands up to EF with 4×5×1022 valence electrons per cm3, giving EF=...
These improvements in dielectric constant and ferromagnetism of the nanotubes by Co2+ doping may be mainly attributed, respectively, to the lattice distortion and the breakage of the spin cycloid period of the BFC nanotubes. 展开 关键词: BiFeO3 Co2+ doping Nanotube ...
In the equation, De is the change in dielectric constant com- pared to the based structure. According to the coupled-mode the- ory22,23, ~Ppert at each point can be thought as a source for a secondary wave. Since all the secondary waves are in-phase, they interfere con- structively ...
Prinz1,3 Dielectrics are an important class of materials that are ubiquitous in modern electronic applications. Even though their properties are important for the performance of devices, the number of compounds with known dielectric constant is on the order of a few hundred. Here, we use Density...

In Eq. (25), the integration constants A2 becomes zero from the periodicity requirement, and A1 can be taken arbitrary (say A1 = 0, because constant electric potential yields zero electric field). Thus, $$\phi (z,t)=\frac{f}{{{a_3}}}{u_{z,z}}(z,t).$$ (34) Furthermo...
