OXYGEN INTERACTION WITH Rh(111) AND Ru(0001) SURFACES: BOND-FORMING DYNAMICS

A new description of bonding and band-forming is presented for the nature and dynamics of O–Rh(111) and O–Ru(0001) surface bonding and its consequences on the behavior of atoms and electrons at the surfaces. The sp-orbital hybridization and electron transportation define that oxygen retains inside the hcp hollow site throughout the course of reaction in which O -1 forms and then O -2 -hybrid follows with production of nonbonding lone pairs and the lone-pair induced antibonding dipoles. Consequently, the valence band and surface morphology are modified with the corresponding features, and the radial and pairing-row reconstruction arises in the corresponding phases.
