We study the low-frequency polarization response of a surface-charged oblate spheroidal particle immersed in an electrolyte solution. Because the charged spheroid attracts counterions which form the electric double layer around the particle, using usual boundary conditions at the interface between the particle and electrolyte can be quite complicated and challenging. Hence, we generalize Fixman...

2014 A method for calculating attenuated total reflection (ATR) spectra of a semi-infinite nonlocal dielectric, in which the effect of the surface is described by a continuous surface potential, is presented. For physically reasonable values of the surface potential parameters the calculated spectra are found to be independent of the choice of the additional boundary conditions (ABC) which are ...

High dielectric capacitor, that has around 1000 in dielectric constant, can be successfully formed by nanotransfer on non-heat-resisting substrates. PZT film could be released from the Si substrate and bonded onto the polymer one. The releasing characteristics have the relationships with the thickness of Pt layer. The formed PZT has perovskite structure and clear columnar texture.

We report on C(60) based organic field effect transistors (OFETs) that are well optimized for low voltage operation. By replacing commonly used dielectric layers by thin parylene films or by utilizing different organic materials like divinyltetramethyldisiloxane-bis(benzocyclo-butene) (BCB), low density polyethylene (PE) or adenine in combination with aluminum oxide (AlOx) to form a bilayer gat...

In this work, different dielectric caps were deposited on the GaAs/AlGaAs quantum well ~QW! structures followed by rapid thermal annealing to generate different degrees of interdiffusion. Deposition of a layer of GaxOy on top of these dielectric caps resulted in significant suppression of interdiffusion. In these samples, it was found that although the deposition of GaxOy and subsequent anneali...

Conditions for the transfer printing of patterned carbon nanotube (CNT) films, along with a Au-gate, a poly methylmethacrylate (PMMA) dielectric layer and Au source-drain electrodes have been developed for the fabrication of thin-film transistors on a polyethylene terephthalate (PET) substrate. Chemical vapor deposition (CVD) grown CNTs were patterned using a photolithographic method. Transfer ...

A hybrid MCM-based 3-D integration technology for packaging intelligent power electronics modules has been developed. The bare power chips are buried in the ceramic frame with dispensed and screen printed dielectric encapsulates. This dielectric coating is designed to achieve planarization and open up the contacts of the power chips. A metallization layer, deposited and patterned on top of the ...

There are a many of needs for the development of SiC-based hydrogen sensor for harsh environment applications. We fabricated and investigated Pd/Ta2O5/SiC-based hydrogen sensors with MOS capacitor structure for high temperature process monitoring and leak detection applications in such automotive, chemical and petroleum industries as well as direct monitoring of combustion processes. In this wo...

Anisotropic colloidal particles constitute an important class of building blocks for self-assembly directed by electrical fields. The aggregation of these building blocks is driven by induced dipole moments, which arise from an interplay between dielectric effects and the electric double layer. For particles that are anisotropic in shape, charge distribution, and dielectric properties, calculat...

Photonics is a branch of science that studies how the light propagatesthrough the material and how to modify its propagation, such as how to prevent thepropagation or to localize the light, which can be useful to amplify the electric field. Toachieve this, one can use a system containing N layers of varying dielectric media inone dimension, which is called multilayer dielectric ...
