Abstract

We report a photoemission spectroscopy study on IrTe2 which exhibits an interesting lattice distortion below 270 K. Ir 4f core-level photoemission spectrum is broadened in going from 300K to 40K. This result indicates the charge moderation of Ir 5d electrons. Angle-resolved photoemission spectroscopy(ARPES) result at 300K shows multi-band Fermi surfaces with six-fold symmetry which are basically consistent with band structure calculations. At the distorted phase, the inner Fermi surfaces become quasi one-dimensional Fermi surface due to the lattice distortion.
