New method to produce graphene nanoribbons could promote use in telecommunications applications

New method to produce graphene nanoribbons could promote use in telecommunications applications University of Wisconsin–Madison researchers have fabricated graphene into the smallest ribbon structures to date, using a method that is said to make scaling-up simple. In tests with these tiny ribbons, the scientists discovered they were closing in on the properties they needed to move graphene toward usefulness in telecommunications equipment. Image credit: University of Wisconsin−Madison “Previous research suggested that to be viable for telecommunication technologies, graphene would need to be structured prohibitively small over large areas, (which is) a fabrication nightmare,” says Joel Siegel, a UW–Madison graduate student in physics professor Victor Brar’s group and co-lead author of the study. “In our study, we created a scalable fabrication technique to make the smallest graphene ribbon structures yet and found that with modest further reductions in ribbon width,

Tiny, Flexible Nanoribbons Could Move Graphene Toward Telecommunication Applications

Telecommunications transmissions, right from radio and television to the internet, are only data transmitted by light waves and changed into electrical signals.

Flexible, easy-to-scale nanoribbons move graphene toward use in tech applications

E-Mail MADISON From radio to television to the internet, telecommunications transmissions are simply information carried on light waves and converted to electrical signals. Silicon-based fiber optics are currently the best structures for high-speed, long distance transmissions, but graphene an all-carbon, ultra-thin and adaptable material could improve performance even more. In a study published April 16 in ACS Photonics, University of Wisconsin-Madison researchers fabricated graphene into the smallest ribbon structures to date using a method that makes scaling-up simple. In tests with these tiny ribbons, the scientists discovered they were closing in on the properties they needed to move graphene toward usefulness in telecommunications equipment.
