    Abstract: Formulations for voltage switchable dielectric materials include two or more different types of semiconductive materials uniformly dispersed within a dielectric matrix material. The semiconductive materials are selected to have different bandgap energies in order to provide the voltage switchable dielectric material with a stepped voltage response. The semiconductive materials can comprise inorganic particles, organic particles, or an organic material that is soluble in, or miscible with, the dielectric matrix material. Formulations optionally can also include electrically conductive materials. At least one of the conductive or semiconductive materials in a formulation can comprise particles characterized by an aspect ratio of at least 3 or greater.

    Abstract: A composition of voltage switchable dielectric (VSD) material that comprises a concentration of core shelled particles that individually comprise a conductor core and a shell, the shell of each core shelled particle being (i) multilayered, and/or (ii) heterogeneous. As depicted, VSD material 100 includes matrix binder 105 and various types of particle constituents, dispersed in the binder in various concentrations. The particle constituents of the VSD material may include a combination of conductive particles 110, semiconductor particles 120, nano-dimensioned particles 130 and/or core shelled particles 140. In some implementations, the core shelled particles may substitute for some or all of the conductive particles. As an alternative or variation, the VSD composition may omit the use of conductive particles, semiconductive particles, or nano-dimensioned particles, particularly with the presence of a concentration of core shelled particles. Thus, the type of particle constituent that are included in the VSD composition may vary, depending on the desired electrical and physical characteristics of the VSD material. For example, some VSD compositions may include conductive particles, but not semiconductive particles and/or nano-dimensioned particles (like carbon nanotube). Still further, other embodiments may omit use of conductive particles.

    Abstract: One or more embodiments provide for a composition that includes (i) organic material that is conductive or semi-conductive, and (ii) conductor and/or semiconductor particles other than the organic material. The organic material and the conductor and/or semiconductor particles are combined to provide the composition with a characteristic of being (i) dielectric in absence of a voltage that exceeds a characteristic voltage level, and (ii) conductive with application of the voltage exceeding the characteristic voltage level.
