What scientific discoveries await the humanity in the future? Today’s fundamental researches are targeted at improvement of information technologies, systems for processing and storing information, as well as at creation of a quantum computer which in many aspects will change the world and people’s lives.

Presently, scientists of South Ural State University are working in this area. In 2018, an article was published in Optics Letters journal, indexed in Scopus and Web of Science databases. The authors of the article are research fellows of the SUSU Laboratory of Functional Materials, Igor Bychkov and Dmitry Kuzmin.

“Our work demonstrates that using the Faraday effect might lead to a sufficiently big value of magnetic field. It is important to notice that creating an electromagnetic field localized in nano scales is a quite serious problem. Our method allows achieving this: to create a big-enough magnetic field which would be localized in a small-enough volume. These magnetic fields in nano scales can be used for various purposes. The most obvious one is magnetic memory for information storage systems,” says Igor Bychkov.

The article considers propagation of electromagnetic waves in a nanostructure which includes a metal substrate, dielectric material and graphene. All elements of micro- and nano electronics are obtained by application of some material (as a rule, metal) on the substrate. It was graphene precisely that the scientists have chosen for the work as its properties are comparatively easy to control: it can change from a practically non-conducting material to a good conductor. This allows obtaining additional functionality of nanostructure.

About the National Graphene Association (NGA)

The National Graphene Association is the main organization and body in the U.S. advocating and promoting the commercialization of graphene. NGA is focused on addressing critical issues such as policy and standards development that will result in effective integration of graphene and graphene based materials globally. NGA brings together current and future graphene stakeholders — entrepreneurs, companies, researchers, developers and suppliers, investors, venture capitalists and government agencies — to drive innovation, and to promote and facilitate the commercialization of graphene products and technologies.
