Published in 2020 at "Scripta Materialia"

DOI: 10.1016/j.scriptamat.2020.08.004

Abstract: Abstract A novel carbon allotrope is predicted by first-principles calculations. This allotrope is obtained by replacing one of the two atoms in the primitive cell of diamond with a carbon tetrahedron, thus it contains five… read more here.

Published in 2020 at "Journal of Materials Chemistry C"

DOI: 10.1039/d0tc04245e

Abstract: Here we proposed a novel two-dimensional (2D) carbon allotrope namely pentagraphyne (PG-yne) which is energetically favourable than other graphyne members, including experimentally synthesized graphyne and graphdiyne monolayer. State-of-the-art theoretical calculations confirm that the new carbon… read more here.
