Dependence of exciton transition energy of single-walled carbon nanotubes on surrounding dielectric materials

open access: yes, 2007
We theoretically investigate the dependence of exciton transition energies on dielectric constant of surrounding materials. We make a simple model for the relation between dielectric constant of environment and a static dielectric constant describing the

Dyes with high dielectric constants [PDF]

open access: yes, 1988
The dielectric constants of perylene dyes, perylene-3,4: 9,10-tetracarboxylic bisimides, are reported. With aromatic substituents, dielectric constants up to 110 are obtained. With polymeric dyes, the dielectric constants rise to 260.

Dielectric properties of hexagonal boron nitride and transition metal dichalcogenides: from monolayer to bulk

open access: yesnpj 2D Materials and Applications, 2018
Hexagonal boron nitride (h-BN) and semiconducting transition metal dichalcogenides (TMDs) promise greatly improved electrostatic control in future scaled electronic devices. To quantify the prospects of these materials in devices, we calculate the out-of-

High-K dielectric sulfur-selenium alloys. [PDF]

open access: yes, 2019
Upcoming advancements in flexible technology require mechanically compliant dielectric materials. Current dielectrics have either high dielectric constant, K (e.g., metal oxides) or good flexibility (e.g., polymers).

Experimental Studies of Antenna Miniaturization Using Magneto-Dielectric and Dielectric Materials [PDF]

open access: yes, 2009
Measurement results for a meandered planar inverted-F antenna (PIFA) loaded with magneto-dielectric and dielectric materials are presented. Figures of merit and ways to compare antennas with different fillings materials are discussed. The used magneto-dielectric material is described, the radiation mechanism of the meandered PIFA is studied, and the ...

Method of forming a multiple layer dielectric and a hot film sensor therewith [PDF]

open access: yes, 1990
The invention is a method of forming a multiple layer dielectric for use in a hot-film laminar separation sensor. The multiple layer dielectric substrate is formed by depositing a first layer of a thermoelastic polymer such as on an electrically ...

Quantized Roentgen Effect in Bose-Einstein Condensates

open access: yes, 1998
A classical dielectric moving in a charged capacitor can create a magnetic field (Roentgen effect). A quantum dielectric, however, will not produce a magnetization, except at vortices.

Identification of structural relaxation in the dielectric response of water [PDF]

open access: yesPhys. Rev. Lett. 116, 237601 (2016), 2016
One century ago pioneering dielectric results obtained for water and n-alcohols triggered the advent of molecular rotation diffusion theory considered by Debye to describe the primary dielectric absorption in these liquids. Comparing dielectric, viscoelastic, and light scattering results we unambiguously demonstrate that the structural relaxation ...
