High and low dielectric permittivity polymer-based nanobybrid dielectric films

Permittivity Measurements of High Dielectric Constant Films at Microwave Frequencies

We have developed a time-domain reflectometry (TDR) technique to measure the dielectric permittivity of high dielectric constant films. The test specimen consists of a planar capacitor terminating coaxial waveguide. The complex permittivity of the dielectric in the frequency domain is obtained from appropriate analysis of the incident and the reflected voltage waves. In order to improve accurac...

Thickness Dependent Dielectric Strength of a Low-permittivity Dielectric Film

The dielectric strength of a promising interlevel low relative permittivity dielectric is investigated for various film thicknesses and temperatures by using I-V measurements with metalinsulator-semiconductor (MIS) structures. It is found that the dielectric breakdown mechanism also depends on thickness. For relatively thick films (thickness >500 nm), the dielectric breakdown is electromechanic...

Dielectric Permittivity and Electric Modulus in Bi2Ti4O11

Dielectric Properties and Morphology of Ferroelectric Ceramic-Polymer Composite Films

Dielectric constant and morphology of BaTiO3-polymer composite films were studied as a function of the filler concentration. The morphology of the films was examined using laser scanning confocal microscopy, which is capable to measure small particle distributions in more details than conventional microscopy. The thin-slice images allowed us to visualize the micronsize particles and the polymer...
