(Bi1-xCex)2Ti2O7 thin films were grown on p-Si 〈100〉 substrates by chemical solution decomposition method. The relationship between the doping levels of cerium ions and the phase transition temperatures was studied. The doping of cerium ions could improve the phase stability of Bi2Ti2O7, and...

Ba0.6Sr0.4TiO3 (BST) and Ba0.6Sr0.4TiO3/Ba(Zr0.2Ti0.8)O3/Ba0.6Sr0.4TiO3 (BST/BZT/BST) multilayer (ML) films were prepared by pulsed laser deposition on the LaNiO3-coated LaAlO3 substrate. X-ray diffraction analysis revealed that the two kinds of films could be epitaxially grown in pure...

We derive the first dynamic correction to the effective refractive index for a square array of cylinders (of finite or infinite refractive index), subject to a low-frequency incident radiation. This correction also imposes constraints on the wave number region for which the Lorentz-Lorenz...

Macroscopic inhomogeneities have a profound effect on electrical conductivity in the presence of a strong magnetic field B. One expression of this is the appearance of a new physical length in the system, which increases with B and is unbounded. This length characterizes the extra distortions of...

The absorption spectrum and density of states of the Drude-Lorentz model of a nonpolar fluid are studied on the basis of a statistical theory. In the dilute limit the shift and broadening of the spectral line and of the density of states, due to dipolar interactions, are described by universal...

The object of this work is to calculate the effective dielectric constant tensor of a warm plasma made of non point-like ions in an electron gas whose screening length is much larger than the inter-ionic and inter-electronic distances. In this disordered medium, a proper treatment of the...

A number of physical and physicochemical properties of granular materials can be traced to the nature of the interfaces and contact between the grains. In this paper we deal more specifically with the electrical resistance of the inter-granular contacts. More generally we will consider the...

The Ge0.15Se0.85 alloy has been prepared in evacuated quartz tubes. Thin amorphous film of Ge0.15Se0.85 system has been prepared by using thermal evaporation technique with 400±5nm thickness. Atomic absorption spectroscopy (AAS) was used to determine the concentration of the composite elements...

In a recent work, Fuentes and Alejandre (2014) found that for TIP4P models there is a dipole moment of minimum density at 240 K and that the Lennard-Jones parameters can be adjusted to match the experimental dielectric constant at 300 K and the temperature of maximum density, respectively. The...
