dielectric constantfrequency dispersionsPLDThe parallel capacitors of YBa2Cu3O7 δ/SrTiO3/YBa2Cu3O7 δ for SrTiO3 with film thickness of 300 nm and 600 nm were fabricated by means of Pulsed Laser Deposition (PLD) and Chemical Mechanical Planarization (CMP) method. In order to investigate the ...
The dielectric constant measured at low frequencies is anomalously large at room temperature but decreases to a limiting value (~25) below about 130 K. A knee observed in the temperature dependence of the conductivity of polycrystalline UO2 corresponds to a process having an activation energy of ...
We have measured the ac properties of polyacetylene doped with H2IrCl6 6H2O and I2 from 10 to 10 Hz at room temperature. We find in both cases that the conductivity is only weakly dependent on frequency, in agreement with previous work. However, we find that the dielectric constant of CH...
The dielectric constant and loss factor of the core samples of the Tipam group form Lakhomoni oil field was studied at different Both dielectric constant and loss factor have shown frequency dependence. While dielectric constant was observed to decrease with frequency, the Loss factor showed more ...
Thus produced chip contains 14 Al–TiW–Pd2Si/n-Si structures with the areas of changing 1 × 10−6 cm2 Results and discussion The frequency dependence of dielectric constant (ε′), dielectric loss (ε″), loss tangent (tan δ), ac electrical conductivity (σac) and electric modulus ...
We have recently been able to find the general relation between frequency and electrical conductance and dielectric constant in mixtures.From our general equation of the force of relaxation one can now derive a detailed discussion of the quantitative limiting laws of the conductivity and the ...
Study results of frequency properties of sapphire and 4H-SiC{0001} silicon carbide substrate show availability of anisotropy and dispersion of effective dielectric constant ε(f). In both cases a value of ε(f) decreases with frequency f increasing. For a sapphire substrate the dispersion (ε(f...
The results revealed that the dielectric constant and dielectric loss increased, whereas temperature and the highest dielectric values were obtained in the case of APS. The density of interconnected pores enwrapped with PPy under the surface improved the electrical/dielectric properties of the composite...
A computer adapted theory for self-consistent calculations of the wavevector- and frequencydependent dielectric constant for interaction site models of polar systems is proposed. A longitudinal component of the dielectric constant is evaluated for the TIP4P water model over a very wide scale of ...
