continues to surprise and fascinate scientists, this time revealing a rare electronic state termed 'ferro-valleytricity', which occurs when graphene is stacked up in a particular five-layer combination., as reported by researchers from the Massachusetts Institute of Technology , Harvard University, and the National Institute for Materials Science in Japan.
show some kind of coordinated behavior in their electric, magnetic, or structural properties – like a magnet, for instance, which has electrons that all spin and point in the same direction without being directed by an external magnetic field., the same material must display multiple types of coordinated behavior.
that had naturally formed into five layers and in this particular pattern, the researchers did indeed see multiferroic behavior.. Second, the electrons showed a tendency to settle in one particular electronic 'valley' , whereas in standard graphene, they don't show any preference.

From a five-layer graphene sandwich, a rare electronic state emergesOrdinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, the material resembles a chicken-wire of carbon atoms linked in a hexagonal lattice.
