Abstract
Atomic and electronic structures of coadsorbed Mg-Ba layers on the Mo( 112) surface have been studied by LEED, LEELS, CDP and UPS (hv = 8.4 e V) techniques. A segregation of Ba atoms is found for adlayers with th ickness beyond one monolayer, which provides a decrease of a work func tion. The coadsorption within the first atomic layer is followed by an effective mixing of the adatoms and no sharp structure at room temper ature is observed.
