Abstract: The surface electronic structure of bismuth-chalchogenide topological insulators interfaced to air or other materials has complex features not predicted by theory. Bahramy et al. propose a model explaining the origin of these electronic states, and uncover their rich spin texture by circular dichroism experiments.
