Abstract
- Abstract: We have examined core-level photoemission spectra of 1T-TiSe2 and 1T-TaS2 to study chemical shifts associated with unusual superlattice formation. While large temperature-dependent core-level splitting was observed for TaS2, temperature-dependent chemical shift was not observed for TiSe2. On the other hand, angle-resolved valence-band photoemission spectra of TiSe2 showed appearance of a new branch (band-folding) at the L points in the ordered phase at 50K. These results suggest smaller lattice distortion in TiSe2 than that in TaS2. [Copyright &y& Elsevier]
