Observation and control of the weak topological insulator state in ZrTe5

Topological side surface, characterization of a weak topological insulator (WTI), has rarely been investigated. Here, Zhang et al. visualize a quasi-one dimensional, spin-momentum locked band on the side surface of the WTI candidate ZrTe5, and manipulate the bulk band gap by strain.
