  text: 'Three-dimensional topological insulators are bulk insulators with Z 2 topological
    electronic order that gives rise to conducting light-like surface states. These
    surface electrons are exceptionally resistant to localization by non-magnetic
    disorder, and have been adopted as the basis for a wide range of proposals to
    achieve new quasiparticle species and device functionality. Recent studies have
    yielded a surprise by showing that in spite of resisting localization, topological
    insulator surface electrons can be reshaped by defects into distinctive resonance
    states. Here we use numerical simulations and scanning tunnelling microscopy data
    to show that these resonance states have significance well beyond the localized
    regime usually associated with impurity bands. At native densities in the model
    Bi2X3 (X=Bi, Te) compounds, defect resonance states are predicted to generate
    a new quantum basis for an emergent electron gas that supports diffusive electrical
    transport. '
