At room temperature and 1 MHz, the dependence of dielectric constant and tunability of the films with electric field were investigated; the dielectric constant and tunability are 725 and 47.0%, 877 and 50.4%, respectively, for the BCZT film on Pt/Ti/SiO 2/Si substrates without and with the...
A (Ba0.24Sr0.76)TiO3 thin film was epitaxially grown on a Pt/MgO(100) substrate by rf magnetron sputtering, and its dielectric properties were evaluated. The thin film had a dielectric constant of 1400 at zero bias field. A drastic decrease of dielectric constant was observed when bias field...
Dielectric dispersion: This is the variation of the dielectric constant with the frequency of the applied electric field. It occurs because different types of polarization mechanisms have different response times to the changing field. For example, electronic polarization, which involves the displacement ...
(separation of charge) is not complete. Under such conditions, thedielectric constantappears to be less than that observed in a direct-currentcircuitand to vary with frequency, becoming lower at higher frequencies. During the alternation of polarity of the plates, the charges must be displaced ...
Dielectric and ferroelectric properties of complex perovskite PZT-PZN ceramic system were investigated under the influence of the compressive stress.The results showed that the dielectric properties,i.e.dielectric constant(ε_r)and dielectric loss(tan δ),and the ferroelectric characteristics,i.e.the ar...
The dielectric properties and the ability of binuclear zinc(II) phthalocyanine of clamshell type compound in passivating silicon (Si) surfaces is studied by fabricating metal–insulator–semiconductor (MIS) capacitors. The frequency and temperature dependence of the dielectric constant were discussed in th...
The ceramics with the composition (0.8)MCoT–(0.2)CSLT sintered at 1200 °C were observed to bear a good combination of microwave dielectric properties; dielectric constant (ε r ) = 26.13, quality factor (Q × f) = 54,820 GHz and temperature coefficient of resonant frequency (τ f ) ...
The a.c. conductivity σ and dielectric properties (dielectric constant ε′, dielectric loss ε′′) were measured at room temperature as a function of frequencies from 10 2 to 10 6 Hz. Also, the variation of loss tangent (tan δ) with frequency was measured. It was found that the ...
Dielectric constant (K) and temperature coefficient of resonant frequency (TCF) decreased linearly with increasing Sm substitution. In the (1- y)Ca2/5Sm2/5TiO3– yLi1/2Sm1/2TiO3 system, the microwave dielectric properties could be controlled by the variation of y. Typical values of K = ...
