Popis: | We report the high-resolution angle-resolved photoelectron spectroscopy (ARPES) experiments and X-ray emission Cr L 2,3 and X-ray absorption (XA) spectra of metallic Cr and Ti in Cr 1/3 TiTe 2 , 1T-TiTe 2 , obtained with the use of linearly polarised synchrotron radiation. The emission spectra are studied at the excitation threshold and beyond it. For the case of beyond-the-threshold excitation, additional bands have been detected. Their origin is discussed on the basis of a model of semi-metallic state of the polarons. Our analysis of angle-resolved photoelectron spectra of Cr 1/3 TiTe 2 with those of 1T-TiTe 2 indicates a formation of narrow and practically dispersionless band situated approximately 1 eV below the Fermi level. |
