Looking inside an endohedral fullerene: Inter- and intramolecular ordering of Dy3N@C80 (Ih) on Cu(111) - Zurich Open Repository and Archive


Treier, M; Ruffieux, P; Fasel, R; Nolting, F; Yang, S; Dunsch, L; Greber, T (2009). Looking inside an endohedral fullerene: Inter- and intramolecular ordering of Dy3N@C80 (Ih) on Cu(111). Physical Review B, 80(8):081403.

Abstract

The inter- and intramolecular ordering of the trimetallic nitride endohedral fullerene Dy3N@C80 with
icosahedral cage symmetry Ih on Cu(111) has been studied by scanning tunneling microscopy (STM) and
synchrotron-based X-ray photoelectron diffraction (XPD). Dy3N@C80 (Ih) is found to form ordered islands
consisting of domains of equally oriented molecules. As for C60 on the same substrate, the cage is facing
with a hexagon towards the surface which is however slightly tilted for C80. The endohedral nitrogen atom
remains at a position close to the geometrical center of the cage. Resonant XPD on the MV edge shows that
the encaged Dy3N unit takes well-defined orientations with respect to the C80 cage and the Cu(111)
substrate.

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.
