| 中文摘要 | We explore the topological behavior of the binary Zintl phase of the alkaline-earth-metal-based compounds Sr(2)Pb and Sr(2)Sn using both standard and hybrid density functional theory. It is found that Sr(2)Pb lies on the verge of a topological instability which can be suitably tuned through the application of a small uniaxial expansion strain (>3%). The resulting nontrivial topologically insulating state displays well-defined metallic states in the Sr(2)Pb(010) surface, whose evolution is studied as a function of the film thickness. |
