Nanofabricated Metamaterial Could be Used in Solar Cells, Nano-Optics

Facebook X LinkedIn Email
A new type of silicon metamaterial that has unique characteristics and is easy to manufacture promises a new direction in the development of metamaterials and their practical application to nano-optics and solar cells. Researchers from the National University of Science and Technology (NUST) MISIS have demonstrated a novel way to manufacture metamaterials by perforating holes in the thin film of silicon or other dielectrics using a focused ion beam (FIB). They found that an FIB can create holes up to 5 nm in size. The result is a dielectric metamaterial that would support the anapole mode...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    metamaterial
    Metamaterials are artificial materials engineered to have properties not found in naturally occurring substances. These materials are designed to manipulate electromagnetic waves in ways that are not possible with conventional materials. Metamaterials typically consist of structures or elements that are smaller than the wavelength of the waves they interact with. Key characteristics of metamaterials include: Negative refraction index: One of the most notable features of certain...
