摘要：
We have used angle-resolved photoemission spectroscopy as a function of excitation energy to elucidate the three dimensionality at the electronic structure of quasi-two-dimensional strongly correlated Cc 4f electron compound CeTe2. We observed that there are two types of Te 5p bands along Gamma Z symmetry line at the valence band, one is non-dispersive bands and the other is dispersive one. While the former is ascribed to the Te 5p bands at two-dimensional Te layer relating to the CDW formation. the latter to one at CeTe double layers. (c) 2006 Elsevier B.V. All rights reserved.
