Electron Energy-Loss Spectroscopy: A versatile tool for the investigations of plasmonic excitations
Friedrich Roth, Andreas König, Jörg Fink +2
The inelastic scattering of electrons is one route to study the vibrational and electronic properties of materials. Such experiments, also called electron energy-loss spectroscopy,…
Plasmon Evolution and Charge-Density Wave Suppression in Potassium Intercalated Tantalum Diselenide
A. König, K. Koepernik, R. Schuster +4
We have investigated the influence of potassium intercalation on the formation of the charge-density wave (CDW) instability in 2H-tantalum diselenide by means of Electron Energy-Lo…
Evidence for phase formation in potassium intercalated 1,2;8,9-dibenzopentacene
Friedrich Roth, Andreas König, Benjamin Mahns +2
We have prepared potassium intercalated 1,2;8,9-dibenzopentacene films under vacuum conditions. The evolution of the electronic excitation spectra upon potassium addition as measur…
Momentum dependence of the excitons in pentacene
Friedrich Roth, Roman Schuster, Andreas König +2
We have carried out electron energy-loss investigations of the lowest singlet excitons in pentacene at 20 K. Our studies allow to determine the full exciton band structure in the a…
The Effect of Charge Order on the Plasmon Dispersion in Transition-Metal Dichalcogenides
Jasper van Wezel, Roman Schuster, Andreas König +4
We investigate the dispersion of the charge carrier plasmon in the three prototypical charge-density wave bearing transition-metal dichalcogenides 2H-TaSe2, 2H-TaS2 and 2H-NbSe2 em…
