Abstract:
1. A device comprising: a layer of voltage switchable dielectric (VSD) material, wherein the VSD material comprises: a polymer binder; a first set of particles consisting of nanoscale high aspect ratio (HAR) particles that are conductive or semi-conductive, the first set of nanoscale HAR particles dispersed within the binder; and a second set of particles, other than said first set of nanoscale HAR particles, consisting of conductor and/or semiconductor particles; said second set of conductor and/or semiconductor particles dispersed within the binder; wherein an amount of particles dispersed in the binder, including the first set of nanoscale HAR particles and the second set of conductor and/or semiconductor particles, is sufficiently low so that a percolation threshold of the VSD material is not reached.
