Abstract

The atomic-scale processes of benzene adsorption and desorption on an Si(111)-7 × 7 surface have been investigated with scanning tunnelling microscopy. Analysis of the atomic-scale images obtained during the adsorption and desorption processes yielded the following results: benzene molecules adsorbed on Si(111)-7 × 7 with the di-σ bonds between molecules and two Si atoms, an adatom and a rest atom; and benzene molecules chemisorb and desorb through physisorption state.
