Graphene. You know may know it as that wonder material that promises to change the way we build roads, craft smartphone screens, kill bacteria or even keep our feet cool. Composed of a one-atom thick sheet of carbon, graphene is thin and highly flexibility, strength and chemical stability. It also conducts electricity 100 times more effectively than copper and moves electrons 140 times faster than silicon (good for fast-charging).
In observing the laser-induced current, researchers found the electrons follow the logic of a quantum system, taking not one but two paths between their initial and excited states. The electrons form a two-state system, traveling simultaneously along two paths to the same end.
