【摘要】In this paper,we investigate topological phases of α-graphyne with tight-binding method.By calculating the topological invariant Z2 and the edge states,we identify topological insulators.We present the phase diagrams of α-graphyne with different filling fractions as a function of spin-orbit interaction and the nearest-neighbor hopping energy.We find there exist topological insulators in α-graphyne.We analyze and discuss the characteristics of topological phases of α-graphyne.
