(credit: Collin Ladd, NC State University) The discovery of graphene—a one-atom-thick sheet of covalently bonded carbon atoms—inspired the research community to generate a variety of 2D materials. Graphene, MoS2, the silicon equivalent of graphene, and more all have distinct properties based on the chemical bonding among their component atoms. […]
