Hardness of T-carbon: Density functional theory calculations
Xing-Qiu Chen, Haiyang Niu, Cesare Franchini +2
We revisit and interpret the mechanical properties of the recently proposed allotrope of carbon, T-carbon [Sheng \emph{et al.}, Phys. Rev. Lett., \textbf{106}, 155703 (2011)], usin…
Strain driven onset of non-trivial topological insulating states in Zintl Sr compounds (=Pb, Sn)
Yan Sun, Xing-Qiu Chen, Dianzhong Li +4
We explore the topological behavior of the binary Zintl phase of the alkaline earth metals based compounds SrPb and SrSn using both standard and hybrid density functional t…
Intrinsic Correlation between Hardness and Elasticity in Polycrystalline Materials and Bulk Metallic Glasses
Xing-Qiu Chen, Haiyang Niu, Dianzhong Li +1
Though extensively studied, hardness, defined as the resistance of a material to deformation, still remains a challenging issue for a formal theoretical description due to its inhe…
