Abstract
A dielectric material for use in electrical energy storage devices includes at least two nanostructures which are each embedded in an electrically insulating matrix made of a material having a bandgap greater than a material of the nanostructures. A probability different from zero of charge carrier tunnelling in parallel to a direction of an electrical field that can be used from outside is set between the two nanostructures.
