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...

Electronic structure of MgB2 from angle-resolved photoemission spectroscopy.

The first angle-resolved photoemission spectroscopy results from MgB2 single crystals are reported. Along the GammaK and GammaM directions, we observed three distinct dispersive features approaching the Fermi energy. These can be assigned to the theoretically predicted sigma (B 2p(x,y)) and pi (B 2p(z)) bands. In addition, a small parabolic-like band is detected around the Gamma point, which ca...

Angle-resolved photoemission and the electronic structure of Pd(111)

A theoretical study of various models which are commonly used for the analysis of angle-resolved photoemission is reported. For the example of the Pd(111) surface we discuss the quality and justification of these models. %e have calculated the @~I-resolved surface and bulk densities of states and the band structure of occupied and unoccupied states. FurtheHIlore, we have calculated photoemissio...

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...
