Polymer/molecular semiconductor all-organic composites for high-temperature dielectric energy storage

Nature Communications, 2020
Dielectric polymers for electrostatic energy storage suffer from low energy density and poor efficiency at elevated temperatures, which constrains their use in the harsh-environment electronic devices, circuits, and systems.

On dielectric membranes [PDF]

Journal of High Energy Physics, 2009
By placing a collection of membranes in 11 dimensional background supergravity six form field and considering the non-linear action of multiple membranes we obtain the potential for transverse scalar fields of membranes and study some possible vacuum configurations.

A novel sol–gel route to synthesize (Sr0.5Ba0.5)Nb2O6 ceramics with enhanced electrocaloric effect [PDF]

Journal of Advanced Dielectrics, 2017
(Sr0.5Ba0.5)Nb2O6 ultra-fine powders were synthesized by a novel sol–gel route, and the mechanism of the reaction was discussed. SrCO3, BaCO3, oxalate niobium and citric acid were used to initiate the sol–gel process, and ethylene glycol (EG) was added ...

Thickness and dielectric constant determination of thin dielectric layers [PDF]

, 1993
We derive a method for the determination of the dielectric constant and thickness of a thin dielectric layer, deposited on top of a thick dielectric layer which is in turn present on a metal film.
