Within a few years of the development of STM as an imaging tool, it became clear that the instrument could also find application in the manipulation of individual or groups of atoms on a surface [M]- Perhaps the most dramatic image originated from Eigler and Schweizer [M], who manipulated single physisorbed atoms of xenon on a Ni(l 10) surface, held at liquid helium temperature ( figure B 1,19,14). The tip-Xe distance was reduced (liy raising the setpoint for the tunnelling current) until the tip-sample interaction became strong enough for the tip to be able to pick up the atom. After being moved to the desired location, the atom was removed by reversing the procedure. Using a similar experimental set-up, Crommie et al [M] have managed to shape the spatial distribution of electrons on an atomic scale, by building a ring of 48 iron adatoms (a quantum corral ) on a Cu(l 11) surface, which confines the surface-state electrons of the copper by virtue of the scattering effect of the Fe atoms ( figure B 1.19.15 ). STS measurements of the local densities of states for the confined electrons correspond to the expected values for a particle-m-a-box , where the box is round and two-dimensional. In a similar way, Yokoyama et al [ ] fonned a pair of long straight chains of Al on the Si (001)-c (4 X 2) surface to create well defined ID quantum wells. The electrons in the FT surface states can propagate only in the dimer-row direction of Si(001)-c (4 x 2) because of nearly flat dispersion in the perpendicular direction. The STM/STS measurements of the standing-wave patterns and their discrete energy levels could be interpreted according to the ID particle-in-a-box model . This teclmique shows considerable promise for the fiirther investigation of confined electrons and waveguides. There are numerous other means for moving atoms in surfaces, including voltage-pulsing teclmiques, which show promise as potential lithographic methods for silicon [68].  [c.1689]
