3D carbon could be metallic

A new form of carbon revealed by theoretical chemistry could have a three-dimensional structure that makes it metallic at room temperature and pressure. Researchers from Peking University, Virginia Commonwealth University and Shanghai Institute of Technical Physics employed state-of-the-art theoretical methods to show that it is possible to manipulate carbon to form a three-dimensional metallic phase with interlocking hexagons. The interlocking of hexagons provides two unique features - hexagonal arrangement introduces metallic character, and the interlocking form with tetrahedral bonding guarantees stability, explains VCU's Puru Jena.
