title = "Hybridization gap in Kondo insulators CeRhSb and CeRhAs studied by ultrahigh-resolution photoemission spectroscopy",
abstract = "Ultrahigh-resolution photoemission spectroscopy (ΔE∼8 meV) has been performed on Kondo insulators CeRhAs and CeRhSb. We found that the 4f-derived density of states shows a depletion (pseudogap) at EF in contrast to metallic Kondo materials. It was also found that the size of both 4f-derived and conduction-electron derived pseudogaps scales well with the Kondo temperature.",
