The modification of polycrystalline MoO 3 surfaces by vapor-deposited Co atoms was studied by means of X-ray photoelectron spectroscopy (XPS). Thin MoO 3 layers react with evaporated Co atoms already at 90 K. At 300 K this process proceeds with a sig

The interaction of CO 2 with a polycrystalline molybdenum-foil (Mo-foil) was previously studied at 77 K through mass-resolved flash thermal desorption spectroscopy (FTDS). From the results, a statistical model was developed with two kinds of sites (b

The interaction of evaporated cobalt atoms with polycrystalline MoO3 surfaces was studied by means of X-ray photoelectron spectroscopy (XPS). In several steps cobalt was evaporated onto the clean MoO3 surface at 300 K. With increasing cobalt layer th

The oxidation of Mo polycrystalline foils at room temperature, through O2-ion bombardment and a reactive O2 plasma studied by XPS and AES, is reported. Samples bombarded with O2 ions showed Mo 3d XP spectra with two broad peaks, which can be deconvol

We report on the electron stimulated adsorption of oxygen produced by the electron beam of an Auger spectrometer on Cu(100) samples at ≈100 K and 300–350 K. The OKLL, as well as the Cu LMM and M23VV Auger signals were monitored. The Cu target was

The interaction of CO 2 with a polycrystalline Mo sheet was studied through Auger electron spectroscopy (AES), mass-resolved flash thermal desorption (FTD) and work function (WF). Above 3 Langmuir (L), three CO 2 desorption peaks can be distinguished

The adsorption–thermodesorption behavior of H 2 O molecules on clean, thin polycrystalline Pd-films has been studied by means of work function (WF) and mass resolved temperature programmed desorption (TPD). Film morphology was varied and stabilized

The interaction of oxygen with thin cobalt films supported on oxidized Si(100) substrates was studied using Auger electron spectroscopy (AES) and work function changes (Δφ) at 130 and 300 K. Oxygen uptake curves were derived from the ratio changes

The growth of evaporated Co overlayers onto Si(100) at 350 K was studied using Auger electron spectroscopy. Cobalt SN was evaporated at a rate of ≃0.4 monolayers/min from a filament. The amount deposited was monitored with a quartz crystal microbal
