Researchers at the Massachusetts Institute of Technology (MIT) have found a new surprising property called ferro-valleytricity in graphene when arranged in layers of five, a press release said. The discovery could help design low-power data storage solutions in the future.

Graphene is the name given to a single layer of carbon atoms arranged in a honeycomb lattice structure, which has found applications in areas as diverse as electronics, composites, space, and biomedical devices.

One could get their hands on graphene by shaving off a regular lead pencil in slices as thin as an atom. In this state, graphene is known to be extremely strong. A team of researchers led by Long Ju, an assistant professor of physics at MIT, has now found that it displays unique electronic properties as well.
