Abstract
Adsorption of trimethylphosphine (TMP) on a Si(111)-(7 x 7) surface ha s been studied using a scanning tunneling microscope (STM). We find th at most of the TMP molecules are adsorbed preferably on center adatom sites at the surface. It is observed that the TMP molecule on a corner adatom is moved to a center adatom site at RT. TMP is more stable on the center adatom sites than on the corner adatom sites.
