Angle-resolved photoemission spectroscopy

The chemisorption bond between CO or NO and Pt is mainly attributed to the interaction of a electron of the adsorbate with the d hole of Pt, whereas the site selection of the adsorbate is assisted by the interaction between the adsorbate 2tt and the Pt 5d orbital. The shape of the d orbital is important for this site selection. The five d orbitals in the Oh space group are generally classified into eg (dx2 y2 and d3,2 r2) and r2g (dxy, dyz, and dM) orbitals with respect to the cubic coordinate. Of the two states of Pt, t2g has more d hole character [90], and furthermore, only the f2g state is upward-shifted and the eg is preferentially filled as a result of s-d hybridization [89]. The d band filling in the eg state due to the s-d hybridization for the alloy is supported by the band structure of this alloy in the Y-L direction observed by angle-resolved photoemission spectroscopy using synchrotron radiation [88]. [Pg.327]

Angle-Resolved Photoemission. The best experimental technique to resolve the electronic structure of crystals in the momentum-energy space, and, consequently, the Fermi surface, is angle resolved photoemission spectroscopy (ARPES). [Pg.472]

More detailed information on the specific orbitals involved in bonding of the adlayer and the symmetry of the bonding site can be derived from angle resolved photoemission spectroscopy (ARPES). With excitation energies of less than 20 eV, the incident photons excite predominantly valence electrons. The valence electron resonances observed are characteristic of band structure of the substrate and the electron orbitals of the adspecies, whose energy is... [Pg.463]

Differing from the conventional s-wave superconductors, the symmetry of the Cooper pair in the HTSC has been established by now to be of d-wave symmetry. Its angular dependence was determined by ARPES (angle-resolved photoemission spectroscopy) to be by Loeser et al. (1996) and (Ding et al. 1996). Furthermore, they have... [Pg.574]
