Statistical and Scaling Properties of the ac conductivity in Thin Metal-Dielectric Composites

We study in this paper the scaling and statistical properties of the ac conductivity of thin metal-dielectric films in different regions of the loss in metallic components and particularly in the limit of vanishing loss. We model the system by a 2D RL − C network and calculate the effective conductivity by using a real space renormalization group method. It is found that the real conductivity s...

Structural and dielectric properties of crystalline and amorphous ZrO2

We first review earlier work in which we computed the first-principles structural, vibrational, and lattice dielectric properties of the cubic, tetragonal, and monoclinic phases of ZrO2 and HfO2. We then discuss two approaches to the construction of realistic models of amorphous ZrO2: a bmelt-and-quenchQ ab-initio molecular dynamics approach, and an bactivation–relaxation techniqueQ. The struct...

Structural and dielectric properties of amorphous ZrO2 and HfO2

Zirconia ZrO2 and hafnia HfO2 are leading candidates for replacing SiO2 as the gate insulator in complementary metal-oxide semiconductor technology. Amorphous versions of these materials a-ZrO2 and a-HfO2 can be grown as metastable phases on top of a silicon buffer; while they tend to recrystallize during subsequent annealing steps, they would otherwise be of considerable interest because of th...

DC conductivity and dielectric properties in silver chloride, revisited.

The anomolous DC ionic conductivity of silver chloride at high temperatures is analyzed quantitatively with the aid of mean field models and classical Monte Carlo simulations. It is found that the conductivity anomaly in silver chloride along with the exponential increase of the dielectric constant at high temperatures may be explained by referring to the idea of a "soft lattice", wherein silve...

Dielectric Relaxation Spectroscopy and AC Conductivity of Doped Poly (Vinyl Alcohol)

The dielectric properties and AC conductivity of pure and doped PVA samples with different concentrations of CuCl2 and Thiourea are investigated in the frequency range from 0.2 Hz to 100 kHz within a temperature range from room temperature to 433 K. It is observed that the dielectric constant decreases with an increase of frequency for all samples. The behaviour of the dielectric loss (ε'') as ...
