Graphene moving towards applications
Graphene, a sheet of carbon just one atom thick, is tough, flexible, transparent and inexpensive, besides being an excellent conductor of electricity: an extraordinary material known to have a huge impact in technology sectors and in our everyday life.
Interested in developing practical applications from graphene, Koppens investigates how this material can convert light into electricity quickly and efficiently. “It is a very useful property,” he says. “For example, to improve solar panels, or the houses can produce their own electricity by placing a graphene coating on the windows.”
In research presented in Nature Nanotechnology, researchers ICFO (Institute of Photonic Sciences of Barcelona) led by Koppens they have shown that graphene converts light into electricity at a scale of femtoseconds (or thousandths of a billionth of a second). “Speed is essential in all communications-related applications, such as mobile phones and computers,” explains Koppens. “To transmit data very fast, need light sensors very fast.”
