Copper Plasmonics Explored for Nanophotonics Applications

Facebook X LinkedIn Email
MOSCOW, March 22, 2016 — Experimental demonstration of copper components has expanded the list of potential materials suited to nanophotonic devices beyond gold and silver. According to researchers from the Moscow Institute of Physics and Technology (MIPT), copper components are not only just as good as components based on noble metals, such as gold and silver, they can be easily implemented in integrated circuits using industry-standard fabrication processes. Gold and silver, as noble metals, may not enter into the requisite chemical reactions to create nanostructures readily and require expensive, difficult...Read full article

    plasmonics
    Plasmonics is a field of science and technology that focuses on the interaction between electromagnetic radiation and free electrons in a metal or semiconductor at the nanoscale. Specifically, plasmonics deals with the collective oscillations of these free electrons, known as surface plasmons, which can confine and manipulate light on the nanometer scale. Surface plasmons are formed when incident photons couple with the conduction electrons at the interface between a metal or semiconductor...
    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.
