Clean vertical line profiles after growth indicate well-defined formation of the IrTe2 film. By using the lattice constant of BLG as a reference we can estimate … See more Figure 2a presents the in situ ARPES intensity maps of ML IrTe2 film taken along the Μ−Γ−Μ direction at 13 K. The ARPES band structure shows an insulating state … See more We further characterized the unexpected insulating ground state of ML IrTe2 using polarization dependent ARPES measurements.
