Decomposition of the total wave aberration in generalized optical systems
Mateusz Oleszko, Ralf Hambach, Herbert Gross
The increasing use of freeform optical surfaces raises the demand for optical design tools developed for generalized systems. In the design process surface-by-surface aberration co…
Mapping atomic orbitals with the transmission electron microscope: Images of defective graphene predicted from first-principles theory
Lorenzo Pardini, Stefan Löffler, Giulio Biddau +4
Transmission electron microscopy has been a promising candidate for mapping atomic orbitals for a long time. Here, we explore its capabilities by a first principles approach. For t…
Anomalous Angular Dependence of the Dynamic Structure Factor near Bragg Reflections: Graphite
R. Hambach, C. Giorgetti, N. Hiraoka +5
The electron energy-loss function of graphite is studied for momentum transfers q beyond the first Brillouin zone. We find that near Bragg reflections the spectra can change drasti…
Linear plasmon dispersion in single-wall carbon nanotubes and the collective excitation spectrum of graphene
C. Kramberger, R. Hambach, C. Giorgetti +12
We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of gr…
