Abstract
A metallic band having the dz2-symmetry was evidenced at the interface between a Cs film and the SrTiO3(001) substrate. The symmetry assignment was carried out with the dipole-transition selection rule, probed by polarization-dependent photoemission spectroscopy. The eg-derived state of the SrTiO3(001) crystal is likely to be a bonding state composed of Cs s-orbital and Ti d-orbital with the eg symmetry, as predicted theoretically.
