By a News Reporter-Staff News Editor at Science Letter -- New research on Nanoribbons is the subject of a report. According to news reporting originating from Taejon, South Korea, by NewsRx correspondents, research stated, "The properties of graphene nanoribbons are dependent on both the nanoribbon width and the crystallographic orientation of the edges. Scanning tunneling microscope lithography is a method which is able to create graphene nanoribbons with well defined edge orientation, having a width of a few nanometers."
Our news editors obtained a quote from the research from the Korea Research Institute of Standards and Science, "However, it has only been demonstrated on the top layer of graphite. In order to allow practical applications of this powerful lithography technique, it needs to be implemented on single layer graphene. We demonstrate the preparation of graphene nanoribbons with well defined crystallographic orientation on top of gold substrates."
According to the news editors, the research concluded: "Our transfer and lithography approach brings one step closer the preparation of well defined graphene nanoribbons on arbitrary substrates for nanoelectronic applications."
