Surface electronic structure of the NdB6„110... clean surface studied by angle-resolved photoemission spectroscopy

An angle-resolved photoemission study of the NdB6(110) clean surface has been done in order to investigate in detail the surface electronic structure. From the dependence of the valence-band photoemission spectra on the surface condition and the exciting photon energy, we found additional peaks corresponding to the surface states on the NdB6(110) surface. These surface states are located at aro...

NaI Aqueous Solution Surface Probed by Photoemission

For a NaI aqueous solution negative surface excess is inferred from the evolution of the ion photoemission signal as a function of the salt concentration. The experiments were performed using a 6μm diameter liquid microjet providing a free vacuum surface, which allows water molecules to evaporate without collisions, and hence enables the direct detection of photoelectrons originating from the l...

Photoemission Study of Diamond ( 100 ) Surface

The electronic structure of the diamond C(lOO)-(2x1)/(%2) has been investigated by means of angle-resolved photoelectron spectroscopy for the first time. A surfacerelated shift has been observed in the C 1s core level spectrum. The surface-state band dispersion was measured along the symmetry axis F-J’ in the surface Brillouin zone. For k,, = 0, there is a-very pronounced surface state 1.5 eV b...

Angle-resolved photoemission investigation of the electronic structure of Be: Surface states.

We have performed an angle-resolved photoemission investigation, using synchrotron radiation, of the surface electronic structure of Be(0001). At normal emission we observe a surface state in the I 3 -I 4. band gap with a binding energy of 2.8+0.1 eV. Away from I it disperses parabolically towards EF with an effective mass of m*/m —1.5. For %co &40 eV, the energy dependence of the photoexcitati...
