英文摘要We present an investigation of the electronic structure of 1T-TiTe2 single crystals using high-resolution angle-resolved photoemission spectroscopy utilizing tunable photon energy excitation. The typical semimetal-like electronic structure is observed and examined, where multiple hole pockets related to Te 5p bands and one-electron pockets related to Ti 3d bands are populated by carriers. The obtained results reveal (i) a pronounced three-dimensional (3D) electronic band structure of 1T-TiTe2 with typical semi-metallic features for both the Ti 3d and the Te 5p states; (ii) multiple Fermi surface sheets and complex band structure; and (iii) an obvious kink in the dispersion at an energy of about 18 meV below the Fermi energy, which is an experimental observation of the kink structure in 1T-TiTe2 single crystal. We find that this kink is induced by electron-phonon coupling in the material. These important and significant findings can help us to gain an in-depth understanding of the 3D electronic structure of semimetallic 1T-TiTe2.
