  • Patent number: 11213974
    Abstract: A method of forming a polyolefin-carbon nanomaterial composite which contains oriented electrically conductive pathways. The method involves milling a polyolefin with particles of a carbon nanomaterial, molding to form a composite plate, and subjecting the composite plate to an AC voltage. The AC voltage forms oriented electrically conductive pathways by partial dielectric breakdown of the composite. The presence of the oriented electrically conductive pathways gives the polyolefin-carbon nanomaterial electrical and thermal conductivity higher than the polyolefin alone.

  • Patent number: 11211559
    Abstract: There is disclosed ultrathin film material templating layers that force the morphology of subsequently grown electrically active thin films have been found to increase the performance of small molecule organic photovoltaic (OPV) cells. There is disclosed electron-transporting material, such as hexaazatriphenylene-hexacarbonitrile (HAT-CN) can be used as a templating material that forces donor materials, such as copper phthalocyanine (CuPc) to assume a vertical-standing morphology when deposited onto its surface on an electrode, such as an indium tin oxide (ITO) electrode. It has been shown that for a device with HAT-CN as the templating buffer layer, the fill factor and short circuit current of CuPc:C60 OPVs were both improved compared with cells lacking the HAT-CN template. This is explained by the reduction of the series resistance due to the improved crystallinity of CuPc grown onto the ITO surface.

  • Patent number: 11189574
    Abstract: A microelectronic package may be fabricated with a microelectronic substrate, a microelectronic die electrically attached to the microelectronic substrate, and an electromagnetic interference shield layer contacting one or both of the microelectronic substrate and the microelectronic die, wherein the electromagnetic interference shield layer has an electrical conductivity between about 10,000 siemens per meter and 100,000 siemens per meter. The specific range of electrical conductivity results in electromagnetic fields either generated by the microelectronic die or generated by components external to the microelectronic package scattering within the electromagnetic interference shield layer and attenuating. Thus, the electromagnetic interference shield layer can prevent electromagnetic field interference without the need to be grounded.
