Graphene, a type of carbon well known for being more grounded than steel and more conductive than copper, can add another marvel to the rundown: making light.
Scientists have built up a light-radiating graphene transistor that works in the same path as the fiber in a light.
"We've made what is basically the world's most slender light," study co-creator James Hone, a mechanical specialist at Columbia University in New York, said in an announcement.
