| heal.abstract | The deposition of Ba on Ni(110) at room temperature was studied by AES, TDS, LEED, as well as SEECC and work function measurements. Ba was found to form a first layer consisting of a mixture of random c(2 X 2) domains and disordered adatoms. The first break in the AES uptake curve is estimated to be similar to 3/4 ML. A second, more weakly bound disordered layer follows. Heating to similar to 200 degrees C turns similar to 0.35 ML to a subsurface phase which is stable up to 800 degrees C. The system becomes mobile at similar to 500 degrees C opening up two kinetic channels: (a) desorption of some of the second layer atoms at similar to 500 degrees C, (b) conversion of the rest of these atoms to long-range c(2 X 2). Finally, desorption from the c(2 X 2) phase occurs at similar to 780 degrees C. The binding energy of the first layer atoms is similar to 2.9 eV at all coverages contrary to alkali metals deposition where it decreases with coverage, whereas the initial dipole moment is similar to 13 D, i.e. similar to the alkali metals. | en |
