Abstract
The atomic-scale processes of benzene adsorption and desorption on an Si(11 1)-7x7 surface have been investigated with scanning tunnelling microscopy. Analysis of the atomic-scale images obtained during the adsorption and deso rption processes yielded the following results: benzene molecules adsorbed on Si(111)-7x7 with the di-sigma bonds between molecules and two Si atoms, an adatom and a rest atom; and benzene molecules chemisorb and desorb throu gh physisorption states.
