Graphene 'could help boost broadband internet speeds'

Scientists from Manchester and Cambridge universities, have found a  way to improve its sensitivity when used in optical communications  systems.

Their discovery paves the way for faster electronic components, such as the receivers used in fibre optic data connections.

Graphene was discovered in 2004 and has been hailed as a "wonder material".

 

Optical communications

The material's use in photo-electrical systems is not new.

Scientists had previously managed to produce a simple solar  cell by placing microscopic metallic wires on top of graphene sheets and  shining light onto them.

Its superconductive properties meant that electrons could flow at high speed with extreme mobility.

However, early graphene solar cells were not very efficient,  as the material was only capable of absorbing about 3% of visible light,  with the rest shining through without being converted into power.

The latest research, overcomes that problem by using a  method, known as plasmonic enhancement, to combine graphene with tiny  metallic structures called plasmonic nanostructures.

 

As a result, its light-harvesting performance is increased by a factor of 20.

"The technology of graphene production matures day-by-day,  which has an immediate impact both on the type of exciting physics which  we find in this material, and on the feasibility and the range of  possible applications," said Prof Kostya Novoselov, one of the lead  researchers.

"Many leading electronics companies consider graphene for the  next generation of devices. This work certainly boosts graphene's  chances even further."

His colleague Professor Andrea Ferrari from the University of  Cambridge added that the results showed the material's "great potential  in the fields of photonics and optoelectronics".

Details of the team's work have been published in the journal Nature Communications.
