Lifetime of quasi-particles in the nearly-free electron metal Sodium
D. V. Potorochin, R. Kurleto, O. J. Clark +8
We report a high-resolution angle-resolved photoemission (ARPES) study of the prototypical nearly-free-electron metal sodium. The observed mass enhancement is slightly smaller than…
Direct observation of charge separation in an organic light harvesting system by femtosecond time-resolved XPS
Friedrich Roth, Mario Borgwardt, Lukas Wenthaus +8
The ultrafast dynamics of photon-to-charge conversion in an organic light harvesting system is studied by femtosecond time-resolved X-ray photoemission spectroscopy (TR-XPS) at the…
Angle resolved Photoemission from Ag and Au single crystals: Final state lifetimes in the as range
Friedrich Roth, Tiberiu Arion, Hendrik Kaser +2
We present angle resolved photoemission spectra for Ag(111) and Au(111) single crystals in normal emission geometry, taken at closely spaced intervals for photon energies between 8…
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…
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…
Dirac states with knobs on: interplay of external parameters and the surface electronic properties of 3D topological insulators
Emmanouil Frantzeskakis, Nick de Jong, Berend Zwartsenberg +19
Topological insulators are a novel materials platform with high applications potential in fields ranging from spintronics to quantum computation. In the ongoing scientific effort t…
