Electronic properties of Mn-Phthalocyanine - C bulk heterojunctions: combining photoemission and electron energy-loss spectroscopy
Friedrich Roth, Melanie Herzig, Cosmin Lupulescu +4
The electronic properties of co-evaporated mixtures (blends) of manganese phthalocyanine and the fullerene C (MnPc:C) have been studied as a function of the concentra…
Low energy exciton pocket at finite momentum in tetracene molecular solids
Friedrich Roth, Markus Nohr, Silke Hampel +1
The excited state dynamics in organic semiconductors plays an important role for many processes associated with light absorption and emission. We have studied the momentum dependen…
Angle resolved Photoemission from Cu single crystals; Known Facts and a few Surprises about the Photoemission Process
Friedrich Roth, Cosmin Lupulescu, Erik Darlatt +2
We present angle resolved photoemission spectra for Cu(100) and Cu(111) singly crystals in normal emission geometry, taken at tightly spaced intervals for photon energies between 8…
Site-specific probing of charge transfer dynamics in organic photovoltaics
Tiberiu Arion, Stefan Nepp, Friedrich Roth +5
We report the site-specific probing of charge-transfer dynamics in a prototype system for organic photovoltaics (OPV) by picosecond time-resolved X-ray photoelectron spectroscopy.…
Electronic excitation spectrum of doped organic thin films investigated using electron energy-loss spectroscopy
Friedrich Roth, Martin Knupfer
The electronic excitation spectra of undoped, and potassium as well as calcium doped phenantrene-type hydrocarbons have been investigated using electron energy-loss spectroscopy (E…
Non-Fermi-liquid scattering rates and anomalous band dispersion in ferropnictides
J. Fink, A. Charnukha, E. D. L. Rienks +13
Angle-resolved photoemission spectroscopy (ARPES) is used to study the band dispersion and the quasiparticle scattering rates in two ferropnictides systems. Our ARPES results show…
