Fig. 4. Atom manipulation by the scanning tunneling microscope (STM). Once the STM tip has located the adsorbate atom, the tip is lowered such that the attractive interaction between the tip and the adsorbate is sufficient to keep the adsorbate "tethered" to the tip. The tip is then moved to the desired location on the surface and withdrawn, leaving the adsorbate atom bound to the surface at a new location. The figure schematically depicts the use of this process in the formation of a "quantum corral" of 48 Fe atoms arranged in a circle of about 14.3 nm diameter on a Cu(lll) surface at 4 K.

Several striking examples demonstrating the atomically precise control exercised by the STM have been reported. A "quantum corral" of Fe atoms has been fabricated by placing 48 atoms in a circle on a flat Cu(lll) surface at 4K (Fig. 4) (94). Both STM (under ultrahigh vacuum) and atomic force microscopy (AFM, under ambient conditions) have been employed to fabricate nanoscale magnetic mounds of Fe, Co, Ni, and CoCr on metal and insulator substrates (95). The AFM has also been used to deposit organic material, such as octadecanethiol onto the surface of mica (96). New appHcations of this type of nanofabrication ate being reported at an ever-faster rate (97—99).

Looks like an alien, said the bartender who served it, wiggling his fingers like antennae on either side of Iris lanky hair. Are you a fan of Wylie s Mr. Dufresne, mutton-chopped and pony-tailed, was visible in the kitchen at the back, corralled like a quarterback by cooks, directing his food into the dining room.

The drawback of the nitride/Cu(100) approach is its narrow application while the principle is sound, the nanoscale nitride corrals only work on copper and a limited number of other single-crystal surfaces. For more realistic applications, a more generic approach is needed. The obvious place to start is to make use of intermolecular forces to control the arrangement of molecules...
