Topological insulators are a newly discovered phase of matter characterized by gapped bulk states surrounded by conducting boundary states 1–3. Since their theoretical discovery, these materials have encouraged intense eeorts to study their properties and capabilities. Among the most striking results of this activity are proposals to engineer a new variety(More)
The realization of quantum spin Hall effect in HgTe quantum wells is considered a milestone in the discovery of topological insulators. Quantum spin Hall states are predicted to allow current flow at the edges of an insulating bulk, as demonstrated in various experiments. A key prediction yet to be experimentally verified is the breakdown of the edge(More)
