Electronic structure at the C60/metal interface: An angle-resolved photoemission and first-principles study - Zurich Open Repository and Archive


Tamai, A; Seitsonen, A P; Baumberger, F; Hengsberger, M; Shen, Z X; Greber, T; Osterwalder, J (2008). Electronic structure at the C60/metal interface: An angle-resolved photoemission and first-principles study. Physical Review B, 77(7):075134-8pp.

Abstract

High-resolution angle-resolved photoemission reveals a complex electronic structure at the interface between a highly ordered C60 monolayer and the Cu(111) surface. The Shockley-type surface state of the clean substrate is pushed to higher energies by the overlayer and strongly couples to intramolecular C60 phonons. A second interface state with a bandwidth spanning the entire HOMO-LUMO gap disperses with the periodicity of the C60 superstructure. Density functional theory calculations indicate that this state is due to strong hybridization of molecular orbitals and substrate electronic states at the C60/metal interface. This finding sheds light on the issue of self-doping in molecular layers on metal surfaces.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
