Observation of metallic surface states in the strongly correlated Kitaev-Heisenberg candidate Na2IrO3

We report high-resolution angle-resolved photoemission spectroscopy measurements on the honeycomb iridate Na2IrO3. Our measurements reveal the existence of a metallic surface band feature crossing the Fermi level with nearly linear dispersion and an estimated surface carrier density of 3.2 \(\times\...
