Detailed insight into the exchange gap spectral structure. (a) Raw ARPES data for Bi0.985V0.015 TeI taken at 20 K, extracted from the data presented in Fig. 1f. (b) Three-dimensional dispersion relation of the Bi0.985V0.015 TeI Rashba-split exchange-gapped surface state at 20 K (the second derivative is shown).
