摘要：
Angle-resolved photoemission results from Nd2-xCexCuO4 (001) single-crystal thin films are reported. The valence-band spectra show a resolution-limited Fermi edge and can be compared to the band calculation to a fair degree, though the main peaks exhibits less well defined dispersion of less than 0.4 eV. A bandlike state of dominant C u 3d character is found just below the Fermi level. It shows well-defined but small dispersion of ∼0.2 eV. There is a possibility of Kondo-type renormalized heavy-electron band formation at the Fermi level. © 1990.
