Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Via deposition of Ph from the gas phase onto a thin, well-ordered alumina film we have prepared various of alumina-supported Rh particle systems. The morphologies and particle sizes have been characterised with spot profile analysis LEED and STM measureme

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In order to investigate how metal growth and metal-oxide interaction depend on the chemical properties of oxide surfaces, we describe a modification procedure which allows the introduction of surface hydroxyl groups on a well-ordered Al2O3 film on NiAl(II

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We present evidence for atomic site-dependent excitonic effects in the x-ray absorption spectrum of an ordered chemisorbed monolayer of C-60/Al(110). We observe that the broadening in the 5t(1u)-derived resonance and the corresponding core level resonant

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We have studied the coadsorption of oxygen with a (2 x 2) monolayer of K on graphite. At least three different adsorption phases for oxygen have been found. Different spectroscopic techniques have been used in order to identify the different oxygen specie

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Bombardment of highly-oriented pyrolytic graphite by energetic monomer and cluster ions (555 eV/atom Ta-1(+), Ta-2(+), Ta-4(+) or Ta-9(+)) is used to introduce surface defects which, after baking in air at approximate to 630 degrees C, nucleate oxidation

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We present a new and general technique with which the local properties of the unoccupied states of an adsorbed alkali atom in the low coverage limit can be studied. The method, based on a combination of experimental core level spectroscopy data and calcul
