Electron pair emission from surfaces: Some general experimental considerations
R. Kamrla, W. Widdra, C. -T. Chiang +1
We discuss some experimental facets of electron pair emission from surfaces using two different experimental approaches. In the first case the instrument consists of a pair of hemi…
Plasmonic Spin-Hall Effect of propagating Surface Plasmon Polaritons in NiFe microstructures
Maximilian Paleschke, Cheng-Tien Chiang, Liane Brandt +3
Photoexcitation and shaping of a propagating surface plasmon polariton (SPP) on silver and gold microstructures are well established and lead to the discovery of the plasmonic spin…
Exchange-striction driven ultrafast nonthermal lattice dynamics in NiO
Y. W. Windsor, D. Zahn, R. Kamrla +7
We use femtosecond electron diffraction to study ultrafast lattice dynamics in the highly correlated antiferromagnetic (AF) semiconductor NiO. Using the scattering vector (Q) depen…
From flat to tilted: gradual interfaces in organic thin film growth
Laura Katharina Scarbath-Evers, René Hammer, Dorothea Golze +3
We investigate domain formation and local morphology of thin films of -sexithiophene (-6T) on Au(100) beyond monolayer coverage by combining high resolution scanning tunnelin…
Ultrafast coupled charge and spin dynamics in strongly correlated NiO
Konrad Gillmeister, Denis Golež, Cheng-Tien Chiang +5
Charge excitations across an electronic band gap play an important role in opto-electronics and light harvesting. In contrast to conventional semiconductors, studies of above-band-…
MnO(001) film growth on Ag(001) - a systematic study using NEXAFS, STM, and LEED
Konrad Gillmeister, Michael Huth, Roman Shantyr +6
The film growth of MnO(001) films on Ag(001) up to film thicknesses of almost seven unit cells of MnO has been monitored using a complementary combination of near-e…
Image potential states of ultrathin NiO films: A time-resolved two-photon photoemission study
K. Gillmeister, M. Kiel, W. Widdra
Well-ordered ultrathin films of NiO have been prepared on an Ag(001) substrate using molecular beam epitaxy. With the help of angle-resolved two-photon photoemission (2PPE) a serie…
Surface phonons of NiO(001) ultrathin films grown pseudomorphically on Ag(001)
K. L. Kostov, S. Polzin, F. O. Schumann +1
For a ultrathin NiO(001) film of 4 monolayers (ML) thickness grown on Ag(001), the vibrational properties have been determined by high-resolution electron energy loss spectroscopy…
Full vibrational characterization of ethylene adsorption on Si(001)-(2x1) by a combined theoretical and experimental approach
Krassimir L. Kostov, Rachel Nathaniel, Tzonka Mineva +1
The vibrational and structural properties of a single-domain Si(001)-(2x1) surface upon ethylene adsorption have been studied by density functional cluster calculations and high-re…
Adsorbate-induced Surface Stiffening: Surface Lattice Dynamics of Ru(001)-(1x1)-O
T. Moritz, W. Widdra, D. Menzel +2
The dynamical properties of the high-density Ru(001)-(11)-O phase has been investigated by a combined high-resolution electron energy loss spectroscopy and density function…
