| 英文摘要 | the structure and properties of sm overlayer and sm/rh surface alloy have been investigated with auger electron spectroscopy (aes), low energy electron diffraction (leed), x-ray photoelectron spectroscopy (xps), and temperature programmed desorption spectroscopy (tds). the growth of sm on rh(100) at room temperature (rt) appears following the stranski-krastanov growth mode and only the trivalent state sm is observed from xps results. thermal treatment of the sm film at 900 k leads to the formation of ordered surface alloy which shows the c(5 root2 x root2)r45 degrees and c(2 x 2) leed patterns. annealing the sm film at temperature above 400 k makes the binding energy (b.e.) of sm 3d(5/2) shift to higher energy by 0.7 ev, which indicates charge transfer from sm to rh(100) substrate, causing the increase of co desorption temperature. |
