Graphene is a single layer of carbon atoms arranged in a honeycomb-shaped lattice and is extremely strong. It is considered a super material and scientists worldwide are researching whether it could be used in advanced circuitry and other electronic devices.
Dr Ferreira said the new method, which is able to assess the impact of billions of atoms for the first time, could help pave the way for faster, more efficient devices.
He said: “It is a game changer and has implications beyond physics. This new method could be beneficial in designing new materials, tailoring them for applications in ‘greener’ computing devices".
“Since it can be applied to study the electrical response of real-size crystal structures, it can help scientists tailor materials for faster and more efficient processing of information in the future.”
“Although we don’t know what materials will be used in next-generation devices we now have a method capable of simulating what will happen to electric signals in complex materials.”
He added: “If we can predict how currents propagate we can build better circuitry and faster processors; it could revolutionise computers.”
