Researchers at the US Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, in Knoxville have developed a novel approach to making two-dimensional, single-atom sheets from two different materials with a seamless boundary. The technique allowed the researchers to combine two of the most exciting substances in materials science today - graphene and boron nitride. People call graphene a wonder material that could revolutionize the landscape of nanotechnology and electronics, ORNL's An-Ping Li explains. Indeed, graphene has a lot of potential, but it has limits. To make use of graphene in applications or devices, we need to integrate graphene with other materials, such as boron nitride. The study, published in the journal Science, might lead to other hybrid 2D materials for various technological applications and fundamental research.
