Figure 1. Temperature evolution of the Dirac cone

Caption

(a) and (b) show the electronic band structures of Bi2Te3 and a magnetic topological insulator sample; the Dirac cone structure is much more prominent in the latter. (c) The two highlighted photoemission peaks and their progressive fusion were ascribed to the closing of the DC gap as temperature increases.
