摘要：
We report on a high-energy angle-resolved photoemission (ARPES) study of the n-type high-T-C cuprate, Nd1.85Ce0.15CUO4 (NCCO). Our bulk sensitive results suggest a hole-like Fermi surface as seen by the so far reported low-energy ARPES studies. The soft X-ray Cu 2p core-level photoemission spectra show clear polar-angle dependence, suggesting the difference in electron states between the bulk and surface. (c) 2005 Elsevier B.V.
