Metallic Tetra-Penta-Hexa Graphene: A Stable Two-Dimensional Carbon Allotrope with High In-Plane Stiffness and Strain-DrivenStructural Transformation
The discovery of novel two-dimensional (2D) carbon allotropes with tailored electronic and mechanical properties remains an important challenge in carbon materials research. Here, we predict a previously unexplored member of the tetra-penta-hexa (TPH) graphene family, termed TPH-M, through particle swarm optimization...
