  • EMI Voltage Switchable Dielectric Materials Having Nanophase Materials
    Publication number: 20110198544
    Abstract: Various embodiments of the invention disclosed herein provide for adjusting the electrical response of a voltage switchable dielectric material by incorporating one or more nanophase materials. Various aspects provide for a VSDM having improved electrical and/or physical properties. In some cases, a VSDM may have improved (e.g., lower) leakage current at a given voltage. A VSDM may have improved resistance to ESD events, and may have improved resistance to degradation associated with protecting against an ESD event.
