We report on the adsorption of atomic C in submonolayer coverages an the Al(111) surface. The local order at the surface is studied for different thermal treatments by means of full-hemispherical X-ray photoelectron diffraction. Deposition at room temperature results in disordered C adsorption while an ordering process takes place after annealing above 475 K. We depict the structure of the annealed C-rich phase. The Cls diffraction patterns are interpreted by comparison with single scattering cluster calculations. The results are discussed with respect to bath previous theoretical ansi experimental work.

Abstract
We report on the adsorption of atomic C in submonolayer coverages an the Al(111) surface. The local order at the surface is studied for different thermal treatments by means of full-hemispherical X-ray photoelectron diffraction. Deposition at room temperature results in disordered C adsorption while an ordering process takes place after annealing above 475 K. We depict the structure of the annealed C-rich phase. The Cls diffraction patterns are interpreted by comparison with single scattering cluster calculations. The results are discussed with respect to bath previous theoretical ansi experimental work.File in questo prodotto:
