Transition-Metal Pentatelluride ZrTe 5 and HfTe 5 : A Paradigm for Large-Gap Quantum Spin Hall Insulators

Year: 2014

Type: article

Abstract: Quantum spin Hall (QSH) insulators, with their insulating interior and conducting edges, have great potential for technological applications. But, scarcity and difficulty in fabrication are major obstacles to their wide applications. Theorists now predict that single sheets that can be exfoliated from two well-known layered thermoelectric compounds, ZrTe${}_{5}$ and HfTe${}_{5}$, are the most promising QSH insulator candidates to date.
