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 states.
