Topological insulating materials with dissipationless surface states promise potential applications in spintronic materials. Through density functional theory, we proposed a new class of topological phase transition in Sb<sub>2</sub>Mg<sub>3</sub> on the basis of tensile strain. At the equilibrium state, Sb<sub>2</sub>Mg<sub>3</sub> corresponds to a normal insulator, and under the influence of tensile strain, the band gaps are gradually tuned. At ε = 7.2%, the nontrivial phase is achieved due to ...[more]
