| Zusammenfassung: | Experimental data for benzene adsorption on chemical vapor deposited graphene/Cu and graphene/SiO2 studied at ultrahigh vacuum conditions are discussed and compared with prior work on physical vapor deposited graphene/Ru(0001). Two widely considered topics, namely, the transparency of graphene and support effects of epitaxial graphene are investigated. Graphene is nearly transparent for benzene adsorption on both copper and silica supports opposed to Ru(0001). In addition, the desorption energy for benzene on epitaxial graphene depends on the reactivity of the support. |
