High Dielectric

The high dielectric constant ferroelectric-polymer nanocomposite was developed for producing the heat-resistant and chemical stable planar layers. According to the composite coatings formation conditions, the following value ranges of dielectric constant and loss factor were received: 30–400 for dielectric constant and 0.04–0.1 for loss tangent, accordingly. Unlike of composite components, the obtained composite material is characterized by thermo-stability of electrical parameters up to 250 °C. The dielectric frequency spectra of the composite exhibit two clearly visible peaks in contrast to the spectra of the polymer and ferroelectric ceramics. The developed composite material can be used as a built-in film capacitors material in microelectronic devices.

High Dielectric

The structures and electronic properties of (LaxAl1-x)2O3 are studied by first-principles calculation method. The results show that the composite material (LaxAl1-x)2O3 tend to be in sixfold-coordinated structure when x0.7. (LaxAl1-x)2O3 is in disorder structure and get the minimum band gap when x equals about 0.7. It suggest that (LaxAl1-x)2O3 can be synthesized as high dielectric constant material by doping La2O3 with a lower Al dopant concentrations or by fabricating (LaxAl1-x)2O3 with rich Al content.
