Abstract
Surface structure, work function changes and plasma losses have been studied for barium films on a Mo(110) surface. At 77 K in the (0.5–0.7)×10 14 cm −2 coverage range, Ba is in a two-dimensional liquid state. Film crystallization leads to the formation of a two-dimensional hexagonal structure with a density of (0.8–1.0)×10 14 cm −2. After a set of coherent structures at a coverage of (1.2–3.6)×10 14 cm −2 the hexagonal structure appears once again. Further Ba deposition occurs within the framework of a monolayer-by-monolayer growth mode. The appearance of the Ba surface plasmon line (2.6 eV) in electron energy loss spectroscopy concurs with the minimum in work function and the coverage location of this appearance shifts as temperature changes. The Ba bulk plasmon loss (6.7 eV) appears when condensation in the second layer begins.
