A method of making a film with a high dielectric constant uses a spin-on sol-gel process to deposit the film on a substrate, the film having a composition (SiO)(TiO), where 0.50 El Khakani My AliSarkar Dilip K.Luc OuelletDaniel Brassard ...
Investigations of electrical conductivity, thermoelectric power and dielectric constant of yttrium titanate (Y2Ti2O7) single crystals are reported in the temperature range from 300 to 1000 K. The compound has been found to be an n-type semiconductor with an energy gap of 3.12 eV. Electrical con...
Next we started a period of build-up of stress by keep- ing the disk at rest and suddenly imparting to the cone a rotation with an angular velocity that was main- tained throughout the period at a constant level sufficiently high to bring about measurable torques and axial forces on the ...

Dielectric loss tangent parameter (DLTP) quantifies a dielectric material's inherent dissipation of electromagnetic energy into heat, expressed by the ratio of dielectric loss factor (imaginary permittivity) to dielectric constant (relative real permittivity), where dielectric constant specifies the amount...
Among all FNPs, the SrTiO3 is well known to be an emerging high dielectric constant ferroelectric material in which the non-ferroelectric transition occurs at a very low temperature (∼105 K) and remains stable in a wide temperature range (∼104–2300 K) without recrystallization [47]...
Substitution of tin for titanium increases the lattice constant at room temperature, and substitution of strontium for barium decreases this parameter. Both types of substitution decrease the Curie temperature; tin is about twice as effective as strontium in this regard. Properties of bodies containing...
[MEANS FOR SOLVING PROBLEMS] The above dielectric article can be produced by a method which comprises mixing a titanium oxide with strontium carbonate or the like, followed by granulating and roasting, to prepare a material, roughly crushing the material by the use of a hummer mill, a roller ...
An improved microwave cavity technique for measuring dielectric constants was used to determine the molar polarization, dipole moment, and nonideality of UF6, freon‐114, C4Cl3F7, and C6H6. Nonideality parameters were calculated for ClF3from previous data. 关键词: Dielectric constant Electric measurem...
All the KTNO samples of varying compositions exhibit high dielectric permittivity (~104) near room temperature, which is comparable to that of the recently discovered CaCu3Ti4O12 (CCTO) ceramic. The high dielectric constant of KTNO depends on both the K and Ti content and can be attributed ...
