Mc. Robinson et Aj. Slavin, INDIUM ADSORPTION ON THE AU(111) SURFACE AT ROOM-TEMPERATURE, Physical review. B, Condensed matter, 54(19), 1996, pp. 14087-14092
Room-temperature studies to determine the growth mode of vapor-deposit
ed indium on the Au(111) surface have been conducted using Auger elect
ron spectroscopy, electron-energy-loss spectroscopy, low-energy electr
on diffraction (LEED), and work-function change measurements. It was f
ound that an alloy, AuIn2, forms from the onset of deposition and the
alloy thickens a layer at a time. LEED results indicate the alloy is d
isordered at the surface. Attenuation lengths for electrons in the all
oy have been determined, as has the stoichiometry. Comparisons are mad
e to Sn on Au(111), studied previously in this laboratory, and to an e
arlier study of In on Au at low temperature.
