Abstract:
The density of two-dimensional Ag adatom gases on W(110) is determined by monitoring local electron reflectivity using low-energy electron microscopy (LEEM). This method of adatom concentration measurement can detect changes in adatom density at least as small as 10−3ML for a μm size region of the surface. Using this technique at high temperatures we measure the sublimation rates of Ag adatoms on W(110). At lower temperatures, where Ag adatoms condense into monolayer islands, we determine the temperature dependence of the density of adatoms coexisting with this condensed phase and compare it with previous estimates.
