Modeling and simulations of diphasic composites for development of high energy density dielectrics
"This research is focused on diphasic dielectric composites for high energy density storage applications in pulsed power and power distribution systems. Composite materials are particularly attractive because they can synergistically combine high permittivity with high breakdown strength of the …

Breakdown in high voltage, high energy density multilayer ceramic capacitors
"Causes of breakdown, both mechanical and electrical, in high voltage, high energy density, BaTiO₃ multilayer ceramic capacitors were studied. The flexural strength of the capacitors was 96 +/- 13 MPa. Failure was due to surface defects or pores close to the surfaces of the samples. The dielectric …

Polymer Composite Dielectric Materials For Pulse Power Applications
… fillers such as barium titanate (BT) for dielectric applications will be discussed. The strategy to overcome the poor filler-polymer interactions that form the core of issue in polymer composites is to surface-modify the filler materials. The attempt by our collaborators at Department of …

Design of Aromatic Thermosetting Copolyester Compositions and Blends for Thin Film Applications
… thin films display sharp improvements in their dielectric properties. Two thin film applications have been investigated. One, because foaming can reduce the dielectric constant, the possibility of foaming ATSP using the reaction byproduct during curing is an attractive concept in developing ATSP …

Switching mechanisms, electrical characterisation and fabrication of nanoparticle based non-volatile polymer memory devices.
… likely to be related to electrode effects, or a breakdown mechanism in the polymer layer. Gold nanoparticle charging via electrostatic force microscopy (EFM) was demonstrated, using a novel device structure involving depositing gold nanoparticles between lateral electrodes. This allowed the gold …
