چکیده

Defect states in different dielectric materials with crystalline and amorphous structures were investigated with two models, the Broer model and the Bloch model. For crystalline structures as in hafnium oxide, defects were found to fit well with the Broer model due to strong local magnetic-field-orientation dependency. In amorphous materials, for example, organosilicate glass, defects were found to fit to the Bloch model due to field broadening effects. Using the two models, behaviors of defects can be described as a result of electron spins. Defect concentrations and locations are determined.

Effect of morphology and nonbounded interface on dielectric properties of plasma sprayed BaTiO3 Coating

In this research, BaTiO3 thick deposit has been successfully sprayed by air plasma spray. The microstructure and dielectric properties of thick films were investigated by secondary electron microscopy (SEM) and LCR meter respectively. XRD measurement was carried out on plasma sprayed BaTiO3. The results illustrate differences in the crystal structure between plasma sprayed coatings and feed sto...

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...

The Relation Between Crystalline Phase, Electronic Structure, and Dielectric Properties in High-K Gate Stacks

As high permittivity dielectrics approach use in metal-oxide-semiconductor field effect transistor (MOSFET) production, an atomic level understanding of their electronic and dielectric properties is being rigorously examined. In our work we illustrate studies leading to such an understanding for the important materials HfO2 and ZrO2. Valence and conduction band densities of states for HfO2/SiO2...

Annealing of Ultrathin Polyethylene Films from Aqueous Dispersions

Introduction Thin and ultrathin crystalline polymer films are of fundamental scientific and practical interest, e.g. in terms of their mechanical properties or of crystallization in a confined environment. A common route to ultrathin crystalline polymer films is spin-coating from solution, often at high temperature, which involves formation of crystalline structures during solvent evaporation. ...

Optical properties of ultrathin films: evidence for a dielectric anomaly at the insulator-to-metal transition.

Optical properties of ultrathin layers (<50 A) of Au and Pb quench condensed on amorphous germanium (alpha-Ge) have been measured in situ at 10 K. The development of these films from an insulating state to a metallic state is traced as a function of the film thickness as well as the sheet resistance, R(square). Of particular interest is the regime of R(square) near 3000 Omega where there is an ...
