Observation of unusual topological surface states in half-Heusler compounds LnPtBi (Ln=Lu, Y)
Abstract
Heusler compounds have been predicted to host topological order with other emergent properties, which yet awaits for experimental evidence. Here, Liu et al. report a direct observation of topological surface states on half-Heusler compounds LnPtBi.
