Uittreksel

Scanning tunneling microscopy (STM) is used to study the STM-tip-induced movement of Co atoms in a dild. Co/Cu(001) surface alloy. By varying the sample temp. from 4 K up to room temp., we measured the threshold temp. at which an incorporated Co atom can be moved, which is approx. 150 K. A vacancy-mediated mechanism is responsible for the obsd. movement, in which vacancies under the tip area exchange with an embedded Co atom. Finally, we present for the first time a selective movement of single Co embedded atoms. [on SciFinder (R)]
