Abstract
One or more embodiments provide for a device that utilizes voltage switchable dielectric material having semi-conductive or conductive materials that have a relatively high aspect ratio for purpose of enhancing mechanical and electrical characteristics of the VSD material on the device.
Claims18
An electronic device comprising:
- a layer of voltage switchable dielectric (VSD) material formed by:
- (i) creating a mixture, the mixture comprising a polymer binder, a first set of conductor and/or semi-conductor particles, and a second set of nanoscale high aspect (HAR) particles other than said first set of conductor and/or semi-conductor particles;
- (ii) applying the mixture to a substrate;
- and
- (iii) curing the mixture on the substrate;
- wherein an amount of particles dispersed in the binder, including the first set of conductor and/or semi-conductor particles and the second set of nanoscale HAR particles, is sufficiently low so that a percolation threshold of the VSD material is not reached.
