Controlled manipulation of ethen molecules and lead atoms on Cu(211) with a low temperature scanning tunneling microscope

We present results of manipulation experiments for single C2H4 molecules and single Pb atoms and buildup of small nanostructures on a Cu(211) substrate employing our temperature-variable scanning tunneling microscope. We further discuss novel ''indirect'' lateral manipulation experiments with C2H4 chains and ph dimers. The latter experiments prove the special stability of Pb dimers. Co-adsorption experiments with CO allow determination of the adsorption sites of C2H4 molecules as well as Pb atoms and Pb dimers. (C) 1996 American Institute of Physics.
