Abstract

The Ce 4f electronic structure of a CDW system CeTe₂ has been investigated using high-resolution angle-resolved photoemission spectroscopy (ARPES). By employing the fine-structure (FS) resonance, the Ce 4f ARPES spectra have been measured. The FS resonance ARPES shows a typical two-peak structure with the peaks at ∼ - 4 and ∼ - 1 eV, in which the latter peak shifts with increasing emission angle by ∼ 300 meV. The Ce 4f states have the negligibly small intensity near E_F, reflecting the minor contribution from Ce 4f electrons to the metallic ground state of CeTe₂. This implies that Te(1) 5p and Ce 5d electrons are involved in the CDW formation in CeTe₂.
