this paper describes the impact of the distance and the size of the corona ring, on the magnitude anddistribution of electrical potential across the polymer insulators. the procedure is based on finiteelement method numerical analysis and stochastic optimization algorithm of differential evolution(de). the optimal selection of corona ring has a significant impact on the control of potential and...

Variations in the band structures of the two-dimensional C60-polymers are studied, when π-conjugation conditions are changed. We investigate the rectangular and triangular polymers, in order to discuss metal-insulator transitions, using a semiempirical model with the Su-Schrieffer-Heeger type electronphonon interactions. We find that electronic structures change among directgap insulators and t...

Poly(ethylene oxide) is demonstrated to be a suitable matrix polymer for the solution-doped conjugated polymer poly(3-hexylthiophene). The polarity of the insulator combined with carefully chosen processing conditions permits the fabrication of tens of micrometer-thick films that feature a fine distribution of the F4TCNQ dopant:semiconductor complex. Changes in electrical conductivity from 0.1 ...

Protection of medium voltage (MV) overhead lines against the indirect effects of lightning is an important issue in Malaysia and other tropical countries. Protection of these lines against the indirect effects of lightning is a major concern and can be improved by several ways. The choice of insulator to be used for instance, between the glass, ceramic or polymer, can help to improve the line p...

An analysis of the demands of ULSI and GSI technologies shows the necessity of multi-layer devices to reduction of signal transmission delay time. This reduction is realized by using a better conductor metal, such as Cu and a surrounding insulator with low capacity than actually used, such as Dow Cyclotene 3022. In this paper, the results of evaporated and sputtered Cu to Dow Cyclotene 3022 wer...

A recently developed theory of atomic-scale local dielectric permittivity has been used to determine the position dependent permittivity profiles of a few nanoscale insulator surfaces and multilayers. Specifically, slabs containing single-component Si, polymer, and SiO2 and two-component Si-SiO2 and polymer-SiO2 systems of technological importance have been studied. The present approach indicat...
