Organic Molecules on Wide-Gap Insulators: Electronic Excitations
Wei Chen, Christoph Tegenkamp, Herbert Pfnür
The electronic excitation of a conjugated molecule-insulator interface, as exemplified by the adsorption of benzoic acid and its phenolic derivative on NaCl(001) surface, is addres…

Monopole and multipole plasmons in a two-dimensional system
H. Pfnür, T. Langer, J. Baringhaus +1
Using monolayer graphene as a model system for a purely two-dimensional (2D) electron gas, we show by energy electron loss spectroscopy, highly resolved both in energy and momentum…
