Three-dimensional topological insulators: A review on host materials

Abstract

In recent years, three-dimensional topological insulators (3DTI) as a novel state of quantum matter have become a hot topic in the fields of condensed matter physics and materials sciences. To fulfill many spectacularly novel quantum phenomena predicted in 3DTI, real host materials are of crucial importance. In this review paper, we first introduce general methods of searching for new 3DTI based on the density-functional theory. Then, we review the recent progress on materials realization of 3DTI including simple elements, binary compounds, ternary compounds, and quaternary compounds. In these potential host materials, some of them have already been confirmed by experiments while the others are not yet. The 3DTI discussed here does not contain the materials with strong electron-electron correlation. Lastly, we give a brief summary and some outlooks in further studies.
