1. A device comprising:

  • a formation of voltage switchable dielectric (VSD) material, wherein the VSD material comprises;

    a binder;

    high aspect ratio (HAR) particles that are conductive or semi-conductive and dispersed as nanoscale particles within the binder; and

    conductor and/or semiconductor particles;

    said conductor and/or semiconductor particles being distributed in the binder;

    wherein HAR particles and said conductor and/or semiconductor particles are combined to provide said 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 said voltage exceeding said characteristic voltage level.
