A Graphene-Metal Sandwich Could Improve Electronics

Researchers have discovered that creating a graphene-copper-graphene “sandwich” enhances copper’s heat conducting properties, which could help in shrinking electronics. Engineers at the University of California, Riverside, and the University of Manchester, UK, in collaboration, found that adding a layer of graphene, a one-atom thick material on each side of a copper film increased heat conducting properties by up to 24 percent.
