Abstract
We carried out an angle-resolved photoemission study of the NdB 6 (110) clean surface in order to investigate the surface electronic structure. From the exciting photon energy dependence and the crud test, we found additional peaks corresponding to the surface states on the NdB 6 (110) surface. The dispersion relations of these surface states were determined along the¯Γ-¯M symmetry line in the surface Brillouin zone. It was found that the energy dispersion for the present surface state is about 250 meV. From these results, we discuss in detail the surface electronic structure of the NdB 6 (110) clean surface.
