Topological states in honeycomb arrays of implanted acceptors in semiconductors

We study a neutral honeycomb array of acceptors in a Group IV semiconductor. Tight-binding exhibits a band gap from different hopping of angular momentum $\pm\frac32$ and $\pm\frac12$ , forming a topological insulator (TI). The hopping is even under separate reversal of spatial and spin motions, unl...
