Off-normal photoemission spectra provide an enhanced surface sensitivity. Near the upper valence band edge, experiment has pointed out an sp z orbital related surface state [8]. Identifying this state, which depends sensitively on the surface geometry, in the theoretical spectra, we can connect...
Figure1(b)shows the XPS spectra of the Ga 3d core level spectra, as well as the valance band of S2, collected at emission angle ofθ= 85° and represented as black dots and lines. By taking Shirley background subtraction and a combination of Gaussian and Lorentzian line shapes, the Ga ...
Kinks in the band dispersions of Sr4Ru3O10 for the sample A1. (a–e) The photoemission intensity spectra measured at different positions in the first Brillouin zone as shown in the inset of each cut. The blue vertical line in the BZ shows the direction in which the cuts were acquired. ...

This spectra can be related to the first electron transition from top of the valence band to the bottom of conduction band along Ŵ − Ŵ direction. For the bulk system an absorption peak of magnitude ∼4.5×105 cm−1 appears at ∼4.0 eV, has zero absorption intensity in the ...
Copper has been reclusive with regard to its plasmonic investigations among the founding plasmonic metals. With the advent of technology and the associated improvements in understanding of plasmonics, copper has been able to make a stand for itself among its peers and even outshine them in a few ...
(A–C) Surface valence-band photoemission spectra of Au-Cu bimetallic nanoparticles (the white bars indicate the d-band centers) (A); proposed mechanism for the CO2RR on the surface of Au-Cu bimetallic nanoparticles (gray, red, and white atoms represent C, O, and H, respectively) (B);...
XPS core level and valence band photoemission spectra for all investigated samples is discussed in terms of changes induced in the electronic structure linked to variation of the Fe2+ cations at the samples surface. This is of fundamental importance to better understand the electronic structure and ...
