217 Abstract—As silicon devices shrink and their density increases, the low dielectric constant materials instead of SiO 2 film is required. SiOC film as low-k films was deposited by the capacitively coupled plasma chemical vapor deposition and then annealed at 300~500 ℃ to find out the properties of the dependence on the temperature and polarity. This study researched the dielectric constant u...

We have found a remarkable increase (up to 60%) of the dielectric constant with the onset of magnetic order at 42 K in the metastable orthorhombic structures of YMnO3 and HoMnO3 that proves the existence of a strong magnetodielectric coupling in the compounds. Magnetic, dielectric, and thermodynamic properties show distinct anomalies at the onset of the incommensurate magnetic order and thermal...

experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-bd, in2-ethyl-1-hexanol, 2eh, were reported for various mole fractions and temperatures (298.2-308.2) kand they were used to calculate dielectric parameters such as kirkwood correlation factor, excesspermittivity and bruggeman parameter. these parameters were used to carry out temperaturedependent die...

The aim of this work is to characterize the dielectric properties of amorphous dendritic macromolecules as a function of architectural complexity. By combining thermostimulated currents and dynamic dielectric spectroscopy, the dielectric permittivity has been obtained as a function of temperature, in a very broad frequency range (10–10 Hz). Generations g = 0 to g = 2 were investigated. The mole...

Amorphous zirconium titanate thin films was prepared on Pt coated silicon substrates by pulsed excimer laser ablation technique at a very low substrate temperature of 200 3OOOC in 0 2 ambient. The temperature and frequency dispersion of dielectric permittivity was investigated on amorphous ZrTiO, thin films. These films exhibited a marked dielectric relaxation at temperatures 500 700 K in a fre...

Polycrystalline samples of Gd-modified Lead Zirconate Titanate [PGZT; Pb1-xGdx(Zr0.65Ti0.35)1-x/4O3] ceramics (where, x = 0.00, 0.06 and 0.09) were prepared using high temperature mixed oxide method at sintering temperature 1450 K. Preliminary structural analysis through X-ray diffraction technique suggests their formation in single phase tetragonal crystal system at room temperature. From the ...

The dielectric properties of Au/Si3N4/n-Si (MIS) structures are studied using the admittance measurements (C–V and G/ω–V ) each as a function of temperature in a range from 80 K to 400 K for two frequencies (100 kHz and 1 MHz). Experimental results show that both the dielectric constant (ε ′) and the dielectric loss (ε ′′) increase with temperature increasing and decrease with frequency increas...

Ionic liquids (ILs) are salts with low melting point close to room temperature. They have interesting solvent properties and are able to dissolve some polar molecules. Polyvinyl formal-IL (1-Ethyl-3methylimidazoliumtosylate) nanocomposite electrolyte with layered filler was synthesized by solution cast technique. Changes in surface morphology have been observed using optical microscopy and scan...

The embedding of oxide nanoparticles in polymer matrices produces a greatly enhanced dielectric response by combining the high dielectric strength and low loss of suitable host polymers with the high electric polarizability of nanoparticles. The fabrication of oxide-polymer nanocomposites with well-controlled distributions of nanoparticles is, however, challenging due to the thermodynamic and k...
