Discovery of a weak topological insulating state and van Hove singularity in triclinic RhBi2

Discovery of a weak topological insulating state and van Hove singularity in triclinic RhBi2

Weak topological insulators (WTI) remain difficult to be observed in experiments. Here, the authors discover a WTI state in RhBi2, where the topological surface states with saddle points result in a van Hove singularity along the (100) direction near Fermi energy.
