CONTROLLED LATERAL MANIPULATION OF SINGLE MOLECULES WITH THE SCANNINGTUNNELING MICROSCOPE

We report on the first successful lateral manipulation of molecules an d controlled formation of nanostructures with the Scanning Tunneling M icroscope (STM) at temperatures above 4 K as used by Eigler and collab orators. Among the first structures, we built the letters F and U form ing the logo of our university at 30 K with CO molecules on a Cu(211) substrate. Our method to manipulate the molecules is analogous to that employed successfully up to now only by Eigler and co-workers, First experiences concerning the manipulation of the CO molecules on the hig hly anisotropic substrate are presented and the crucial role of the ti p composition in imaging the CO molecules is demonstrated.
