Unoccupied electronic structure of TiOCl studied by x-ray absorption near-edge spectroscopy

Sebastian Glawion, Maurits W. Haverkort, Götz Berner +6

We study the unoccupied electronic structure of the spin-1/2 quantum magnet TiOCl by x-ray absorption near-edge spectroscopy (XANES) at the Ti L and O K edges. Data is acquired bot…

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…

Electronic excitations of potassium intercalated manganese phthalocyanine investigated by electron energy-loss spectroscopy

Benjamin Mahns, Friedrich Roth, Mandy Grobosch +2

The electronic excitations of manganese phthalocyanine (MnPc) films were studied as a function of potassium doping using electron energy-loss spectroscopy in transmission. Our data…

The catalytic potential of high-k dielectrics for graphene formation

Andrew Scott, Arezoo Dianat, Felix Börrnert +8

The growth of single and multilayer graphene nano-flakes on MgO and ZrO2 at low temperatures is shown through transmission electron microscopy. The graphene nano-flakes are ubiquit…

Dynamic response and electronic structure of potassium doped picene investigated by electron energy-loss spectroscopy

Friedrich Roth, Benjamin Mahns, Bernd Büchner +1

We performed electron energy-loss spectroscopy studies in order to get a deeper insight into the electronic properties of potassium intercalated picene, a recently discovered super…
