A metallic band having the d z 2 -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 e g -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 e g symmetry, as predicted theoretically.
