An RF electromagnetic (EM) characterization of high pulsed voltage electrode is investigated in the present paper. The electrode acts as an electric-or E-field pulse generator for atom probe tomography (APT) application. The proposed electrode device is essentially comprised of a microstrip transmission line (TL) combined with via hole. The challenging prediction of the electrode signal integrity...
Organic and polymer-based resistive memory cell sandwiched between two vertically aligned electrodes constitute crossbar memory arrays in which the building blocks, referred to as bit cells, possess two or multiple stable resistance states.1 They are promising circuit elements due to their good scalability and processability, high possibility of molecular design through chemical synthesis, high storage...
Polyethylene has been widely used as the insulation of high voltage power cables due to its excellent dielectric properties and electrical performance. The existence of space charge in polymeric insulators is a significant issue with respect to life expectation. It can alter the local electric field and initiate possible partial discharge or eventual breakdown. This appears relatively more severe...
A bipolar charge transport model has been developed to simulate the dynamics of space charge under dc fields. The modeling shows space charge build-up and decay comparable to experiments. In this paper, this bipolar charge transport model is taken further to simulate the space charge in polyethylene under ac fields. The results show that there is small quantity of phase-dependent bipolar charge accumulation...
This paper reports on the investigation into space charge characteristics at interfaces of multi-layer polymeric materials. Planar low density polyethylene (LDPE) samples were used in this study. DC voltage up-to 10 kV was applied to the sample and space charge measurements were taken using the pulsed electro-acoustic (PEA) technique. Experimental results indicated that the electrode interface plays...
