Abstract
We present scanning tunneling microscopy and spectroscopy measurements of the charge-density wave state in 1T-TiSe2, Cu0.05TiSe2, and Cu0.06TiSe2 single crystals. Topography images at 4.2 K reveal that the charge density waves are present in all samples studied, although the amplitude of the charge modulation decreases with the Cu doping. Moreover, the chiral phase of the charge density wave is preserved also in Cu-doped samples. Tunneling spectroscopy shows that there is only a partial gap in the pure compound, with bands crossing the Fermi surface. In the Cu-doped samples, the system becomes more metallic due to the increase of the chemical potential.
