The longitudinal dielectric constant is calculated for the extended Bardeen-Cooper-Schrieffer model of a superconductor. An explicit formula is obtained, which can be evaluated numerically. The competition between collective and single-particle effects is pronounced, so that the dielectric finction differs...

We discuss possible applications of the experimental measurements of the dielectric constant as a probe of the phase-structure state of a composite material.关键词: Theoretical or Mathematical/ composite materials dielectric materials metals permittivity/ dielectric constant dielectric anomaly tool probing ...
This structureless transition of (TMTTF) 2SbF 6 (T c = 154 K) and of (TMTTF) 2ReO 4 (T c = 220 K) is reflected by a divergence of the dielectric constant contrasting with a stepwise decrease at the ordering of the ReO 4 anions (T c = 160 K). These data support the pseudo-...

In ultra large-scale integrated circuit(ULSI ),with the improv ement of the integration and the decrease of the interconnection delay,a new w iring material with low resistance and a new interlayer insulator with low diele ctric constant (k=1～3)which is called low-k materials are required...
Dielectric dispersion: This is the variation of the dielectric constant with the frequency of the applied electric field. It occurs because different types of polarization mechanisms have different response times to the changing field. For example, electronic polarization, which involves the displacement ...

(Garget al., 2018). However, high remnant polarization results in a high loss during the energy storage, and the effective dielectric constant will reduce with the increase of the electric field. Some ceramics for example BaTiO3, PbTiO3, etc. are ferroelectric; PVDF is the most well-known...
