  • Weak antilocalization is a signifier of electrical transport via topologically non-trivial surface states of a topological insulator, but it is often masked by dopant-induced scattering. Kim et al.overcome such difficulties to identify coherent transport via the topological surface states of bismuth selenide.

  • Despite their name, the bulk electrical conductivity of most topological insulators is relatively high, masking many of the important characteristics of its protected, surface conducting states. Counter-doping reduces the bulk conductivity of Bi2Se3 significantly, allowing these surface states and their properties to be clearly identified.

  • Topologically non-trivial states usually emerge from systems with strong spin–orbit coupling, but evidence for such states in the Kondo insulator samarium hexaboride suggests that they can also be driven by strong electron correlations.
