Momentum-resolved electron energy-loss spectroscopy of graphene
In this work, we conduct a detailed experimental investigation and discussion of the full momentum-dependent response of graphene, that is, we directly measure the pi and pi + sigma-plasmon dispersion in free-standing ...
Dielectric properties of graphene/MoS2 heterostructures from ab initio calculations and electron energy-loss experiments
(Universität Ulm, 2018-06-07)
High-energy electronic excitations of graphene and MoS2 heterostructures are investigated by momentum-resolved electron energy-loss spectroscopy in the range of 1 to 35 eV. The interplay of excitations on different sheets ...
