Angle-resolved ultraviolet photoemission spectroscopy

Angle-resolved ultraviolet photoemission spectroscopy ARUPS Electrons photoemitted from the valence and conduction bands of a surface are detected as a function of angle. This gives information on the dispersion of these bands (which is related to surface structure) and also structural information from the diffraction of the emitted electrons. Valence band structure... [Pg.4729]

The surface dissociation of COj into CO(ads) and O(ads) has been proposed in the case of Na-modified Pd(lLl) and K-modified Pt(lll) 5 at submonolayer coverage on the basis of HREELS , and angle resolved ultraviolet photoemission spectroscopy (ARUPS). 59 pyjg presence of adsorbed atomic oxygen (a species capable of migrating into the bulk metal) for Na/Pd(lll) however, could not be detected with either of these techniques.

By varying the angle of incidence of the electrons their momentum (k) can be varied to produce band maps of the unoccupied states as a function of momentum that are analogous to those of the occupied states produced in angle-resolved ultraviolet photoelectron spectroscopy (ARUPS). This is known as k-resolved inverse photoemission spectroscopy (KRIPES) or angle resolved inverse photoemission spectroscopy (ARIPES). [Pg.537]

With the availability of intense tunable radiation in the range firom ultraviolet to hard X-rays from synchrotrons, powerful new experimental techniques have been developed to probe the structural and electronic properties of solids and surfaces. In particular, angle-resolved photoemission gives information about the electronic properties in the valence bands of solids while core level spectroscopy provides an element-specific spectroscopic tool.
