Description

Research Topic Description, including Problem Statement:

The goal of this research is to develop novel materials to secure information from surveillance with a particular focus on windows. Historically, it has been difficult and expensive to build windows with a high level of transparency in the visible spectrum that effectively block electromagnetic radiation from the rest of the spectrum. There are a limited number of products on the market for just such a purpose. Low emissivity or low-E films, while not explicitly designed for this purpose, do offer some degree of radio frequency (RF) attenuation. Coincidentally, there has been an explosion of research in the area of graphene and other 2D materials such as the dichalcogenides because of the large achievable mobilities and tunable bandgaps. Such materials appear to have promise for the tunable, frequency dependent attenuation of electromagnetic radiation. In particular and in contrast to traditional materials, 2-D materials have demonstrated that the higher the dc conductivity, the more visibly transparent they become. Beyond the difficult problem of optimizing the tailored response over the entire frequency range, scalability will also be a major challenge. A second focus could the development of smart windows that adapt to their environment or that act to serve a dual function such as detection of surveillance attempts.

Example Approaches:

  • Graphene can be doped passively by contact with other materials such as sodium glass to enhance the DC conductivity. Chemical vapor deposition (CVD) is a scalable technique to grow graphene on copper foils. Glasses or other dielectrics can be applied by the “spin-on” technique.
  • Multiple layers of different 2D materials such as graphene and polyethylene terephthalate (PET) could be utilized to enhance performance.
  • 2D materials could be combined with metal meshes and/or metal/dielectric layers to enhance performance. Metal meshes can be fabricated with traditional photolithography.
  • Hyperthermal ion implantation (HyTII) could potentially be used to further dope graphene and other 2D materials. Multiple beam systems could allow such an approach to scale to large surfaces.

Relevance to the Intelligence Community:

If successful, results will improve the ability to prevent electromagnetic transmission of information into and out of its secure facilities.
