Atom-specific spin mapping and buried topological states in a homologous series of topological insulators

Strategies to tune the surface properties of topological insulators are essential, if they are to find use in applications. Using a combination of theoretical and experimental techniques, this study examines how the properties of ordered ternary topological insulators vary with the content of group IV elements.

Prediction and observation of an antiferromagnetic topological insulator

An intrinsic antiferromagnetic topological insulator, MnBi₂Te₄, is theoretically predicted and then realized experimentally, with implications for the study of exotic quantum phenomena.
