h-C63: A new hexagonal superhard metallic carbon allotrope
Carbon is known to form a number of allotropes due to its ability to exist in different hybridizations. Here, based on first-principles calculations combined with crystal structure searching method, a new hexagonal carbon allotrope named h-C63 was proposed. The calculated elastic constants and phono...
