Abstract

The postadsorption of 0.25 monolayer of Cs on oxygen-precovered Ru(0001) surfaces with various coverages ranging from 0.25 to 1 results in the formation of metastable (Formula presented) overlayers. These systems are characterized by only minor changes of the electronic and structural characteristics of the Cs subsystems, due to the presence of coadsorbed oxygen. This indicates a quite weak interaction between the two subsystems as judged from thermal desorption spectroscopy, metastable deexcitation spectroscopy, low-energy electron diffraction measurements, and density-functional theory calculations. The main reason for the development of such metastable phases is seen in the strong O-Ru bonding which is superior to the Cs-O interaction.
