  • Patent number: 11705535
    Abstract: A nano-indent process for creating a single photon emitter in a two-dimensional materials platform comprising the steps of providing a substrate, providing a layer of polymer, providing a layer of two-dimensional material, utilizing a proximal probe, applying mechanical stress to the layer of two-dimensional material and to the layer of polymer, deforming the layer of two-dimensional material and the layer of polymer, and forming a nano-indent in the two-dimensional material. A single photon emitter in a two-dimensional materials platform comprising a substrate, a deformable polymer film, a two-dimensional material, and a nano-indent in the two-dimensional material.
    Type: Grant

  • Publication number: 20200153090
    Abstract: A plasmonic patch antenna is provided that includes an arbitrary substrate with an optically thick ground plane proximate to the substrate. A first dielectric material with a first refractive index is proximate to the ground plane. A second dielectric material with a second refractive index is proximate to the first dielectric material. A periodic array of conducting rectangles is proximate to the second dielectric material. The first refractive index is greater than the second refractive index and a thickness of the first dielectric material is greater than a thickness of the second dielectric material.
