Abstract:
The dependences of the work function of ytterbium nanofilms with a thickness ranging from 1 to 32 monolayers on the amount of CO or O2 molecules chemisorbed on their surface have been investigated experimentally. It has been found that these dependences have a pronounced nonmonotonic character. The mechanism of the Yb2+→ Yb3+ valence transition, which occurs upon the chemisorption of CO or O2 molecules on the surface of ytterbium nanofilms, has been developed using the results of this study together with the previously obtained data.
