Abstract
Exposure of a Ru(0001) surface covered by submonolayer quantities of Cs to O2 leads to the emission (with very low probabilities) of O ions. The yield of O reaches a maximum at Cs coverages around 0.3–0.4 monolayers (1 ML is equivalent to an absolute coverage θCs = 0.33), and in this range is much higher for low (∼260 K) than for high sample temperatures. These effects are traced back to the varying degree of “metallization” of the Cs overlayers as substantiated by metastable deexcitation spectroscopy (MDS) experiments.
