GROWTH STUDY OF SILVER ON MGO(100) MO(100)

We report on ultra-high-vacuum depositions of thermally evaporated sil ver at different temperatures and coverages on a well-characterized th in magnesium oxide film, which is supported on a molybdenum single cry stal. From electron energy loss (EELS, HREELS) and photoemission spect ra (UPS, XPS), we propose a three-dimensional growth mode at room temp erature. From temperature-dependent measurements between T=100 and 500 K, we deduce the sticking probability, S, for this system. (C) 1998 E lsevier Science B.V. All rights reserved.
