In addition, these authors used a technique called angle-resolved photoemission spectroscopy to study the electronic structure at the material’s surface.

Using angle-resolved photoemission spectroscopy, we observe a pair of quasi-two-dimensional Dirac cones near the Fermi level with a mass gap of 30 millielectronvolts, which correspond to massive Dirac fermions that generate Berry-curvature-induced Hall conductivity.
