Topological Dirac semimetal phases in InSb/$\alpha$-Sn semiconductor superlattices

Jian-Peng Sun, Jia-ji Zhu, Dong Zhang +1

We demonstrate theoretically the coexistence of Dirac semimetal and topological insulator phases in InSb/$\alpha$-Sn conventional semiconductor superlattices, based on advanced first-pr…
